THIS MADE ME HATE MY ABARTH 595 COMPETIZIONE!! *250 BHP Power Loss*

[@efferus]

Can confirm your issue Stef, my Abarth was suffering some odd performance issues when I found out the upstream sensor was chewed through by an aftermarket intake that had been rubbing on and eventually consumed through the wires related to the sensor. A quick replacement and things were back to proper functioning order! Cheers.

[@StefABtv]

Thanks mate. Yeah glad it was a simple fix!

[@klasseact6663]

Glad it's all sorted out Stef! I've had a random CEL the past 2 days, 3 codes in fact. One is the MAP, the other is low psi and the last one is throttle acuator control system. When it first came on it went into lymph mode, 5 psi. Got to where I was going, shut it off and the light remained after restart but full 18 psi. The next day no light...until 8 got down the road again, along with electronic throttle control, NO driveability issues. Pulled over, turned off the car and upon restart no light for the electronic throttle control, LOL, CEL remained. I then drove to the local auto parts store to have the code read, drove fine, light still on but went into lymph mode at some point. The code reader gets plugged in and then the car is restarted and....NO CEL, LOL. The info was gathered and I got a sheet with the 3 codes. Started the car and no CEL...until a minute later, sitting there and drove home where it boosted just fine. I removed my K&N open element air filter and cleaned it and blow dried it and let it sit and lightly re-oiled it. Now it sits for a day until I drive it again, we will see how it goes. I should also mention it's gotten pretty hot outside once again too. I may have to have the throttle body removed and cleaned out next if the issue persists, thanks for reading my mini novel.

[@StefABtv]

Hopefully that solves it for you mate! Thanks for watching as always!

[@twostrokeandsawdust]

Great video Stef, I had a similar issue. Basically the AFR (air fuel ratio sensor) is a little bit temperamental on my 500. You get the same situation if you put E85 fuel in without the tune or the injectors to suit. Basically the sensor limits your boost and winds the timing back to help prevent dangerous air/fuel ratios screwing the engine.

[@StefABtv]

Thank you mate!

[@richardtraut1431]

All is great once again in the end ,thankfully not to much was replaced and the issue found pretty quickly so well done to the guys sorting and narrowing it down so fast .These modern day turbo charged vehicles are so much more complexed compared to my back in it`s day little hot hatch Fiat Uno 1.3 turbo ie :))))

[@StefABtv]

Thanks mate :) glad it’s sorted!

[@davespooney8472]

Thank you Stef, always a good thing posting solutions to problems. The sensor looks battered, I take it the air/fuel is now spot on? Your kinda lucky, if you ever feel there’s an issue somewhere get it sorted ASAP. That little engine is producing a lot of power and it won’t take kindly to lean conditions.

[@StefABtv]

Yeah all is good now :)

[@learnmyname123]

Great video with helpful advise. Im gonna get my sensor checked as im experiencing similar issues. Also thanks for not fluffing it to 10 minutes so you could monetize it. Kudos.

[@StefABtv]

Thank you 🙏

[@learnmyname123]

Hey guys look I'm famous! Stef ABtv actually acknowledged my post! Im never washing this hand!

[@QandBVlogs]

Benny Carpenter-Deason yeah he definitely shouldn’t be paid for taking a couple of days out his social life every week and making us this video plus the numerous hours for editing. 😩

[@learnmyname123]

QandB Vlogs not that he shouldnt, but he didnt force it.

[@Jamie7ee]

Is that how it goes then?! 10mins plus and money is earn’t? Never knew that.

[@HenzPowell]

Came back to the channel after a few months of not watching videos and you've gained 2k of Subs! Well done! Plus your filming is better!

[@StefABtv]

Thank you! 🙌

[@charlesclement383]

Thanks for your advise. I have an Abarth,and plan on a turbo upgrade very soon. Already did much work to it. Thanks. Good Luck.

[@thargor6750]

I got an abarth! Brutal first week, been in the shop for three days... hopefully they figured it out now.

[@StefABtv]

Hope it’s sorted!

[@Ohlukei]

My 595 Turismo series 3 (IHI charger) has an issue from day one (brand new). Sometimes when I press full throttle the turbo pressure falls down to 4,3 psi (0,3 bar) or 5,8 psi (0,4 bar) for three seconds which is almost NOTHING. During that time I get almost no power. On warranty Abarth replaced the wastegate, the boost pressure control valve and the diverter valve with no success. Abarth itself never noticed any issues which made analysing the issue difficulty. Even after an 200 hp modification with a bigger turbo and a completely new, professional software setup this issue is still happening (and some new where at 170 kph and 30 % throttle it often runs far better than at full throttle). Now I always start with 2/3 or 3/4 throttle to avoid the power loss. After two and a half year of searching for the issue and I finally gave up on it. -.-

[@bobbik]

Fantastic video,quality as usual. Informative solution to a problem. Think we should have a channel just for problem solving, especially for the UK.👍

[@StefABtv]

Thanks mate :)

[@JoshKemponcars]

Great video Stef, sounds like an absolute beast!

[@StefABtv]

Thanks Josh

[@DB-nm4hf]

which turbo have you got fitted on the car?

[@Antara755]

This guy is really in love with his car.

[@levibelgium5406]

Hi Stef. Thank you very much for sharing this issue on the lambda sensor. I might face the same problem with my 595 Pista. In the beginning it was ok with his standard 160 Hp. Afterwards I noticed that "my guts" started to say "hey it's not as fast anymore as it used to be". Two weeks ago I went to the tuner to do a remapping. But they came to me and asked me "don't you normally need to have 160 Hp and 230 Nm of torque? We can only get it up to 134 Hp and 217 Nm before the remapping". So I was very surprised and angry at the same time on ABARTH. But after the remap it went up to 164 Hp and 314 Nm. A really big change and I was happy again. But now my guts are starting again to say that it's getting slower again... I also noticed that when the car is colder that it's more awake/agressive in accelleration. Sometimes when I stayed for a while around the same rpm and I pushed the accellerator to the metal, he accellerated very slowly. They checked it at the garage but nothing to report. So watching your video now will make me go to the ABARTH garage and tell them that it might be the lambda sensor. If necessary I'll show them your video. I have my Pista from last year october and it is still under garantee. Now I'll be gone for 3 weeks but after that I'll go straight away to the garage and I'll keep you informed about what they'll say. Thanks again for sharing, keep up the great channel, enjoy the ABARTH and until next time! Cheers!

[@StefABtv]

Thank you mate :) hope It gets sorted :)

[@evrenenver5874]

Wasapnin Stef winning again yea...😁 I’m still winning bro great vid 👌🏽nice 1 👍🏼

[@StefABtv]

Thanks man!

[@jamesjack6769]

You speak so quick I couldn't make out the name of your tuner. Thinking of buying one of these cheeky wee things.

[@QandBVlogs]

Great informative video keep it up Stef 💪🏽

[@StefABtv]

Thank you!

[@fernandonavarretemadrona937]

The lambda sensor needs a high temperature for make a good work (300° C, for that they have a small heater inside) maybe that's the reason because the car didn't work well in winter

[@StefABtv]

Yeah that’s what we thought too mate.

[@jat5828]

Similar sensor went on mine , great it’s sorted btw remember “- power corrupts, absolute power corrupts absolutely!”lol

[@StefABtv]

Haha :)

[@אמיראבני-נ7ס]

Hi ,is this the pre cat or after cat that was inop?

[@mihaialexns]

You had yellow engine light before u change lambda sensor ? or only the car was slower , the only one sympthom ?

[@stevenhearnden6103]

Anything that 'fettled' will need quite a bit of attention. Worth it though! 😁

[@StefABtv]

Oh yes :)

[@JayEmmOnCars]

I NEVER noticed your car had a moonroof before

[@StefABtv]

😂

[@bomfunk77]

Did your car have the odd stutter at idle as well as the kettle sound on boost before changing sensor? As this is very similar problem ive been having and been convinced it was a boost leak.

[@StefABtv]

It had a little stutter once or twice too yep.

[@bomfunk77]

Thanks for the info Stef, and love your little beast

[@LUSFNA48]

Thanks for the great Video. I just got my 500 Abarth and I put a stage 3 Road Race MotorSport mod in the car with a high flow down pipe with Cat and now my engine light goes on, do I need to put the stock cat back on to solve the engine light issue?

[@StefABtv]

Thanks for watching!

[@harrykaloulis7543]

Yes, unless you go to a tuner and he makes a custom tune for you that bypasses the de-cat.. but that would mean you wasted your money on that tune you have..

[@LUSFNA48]

Harry Kaloulis thank you for your reply. Yeah I have to get Road Race to see if they can fix it, if not, then refund me for that job done.

[@sccobyste]

What roof spoiler did you have on the comp

[@jamiesweeting1770]

What's the deal with the ash breather filter on the recirc valve mate ? Did that put the engine light on or will it be ok to do on a car that just has the forge induction ?

[@boostedandbolted6890]

Jamie Sweeting you can put them with a standard air box, just blanket he recirc pipe that goes into it, no engine light

[@StefABtv]

No eml with it mate. Just vents to the atmosphere rather than back through the intake

[@greenneon7314]

I really wish we could get those seats in the USA. Btw how tall are you (I'm 6'3") I tried a few test drives and my head hits the roof even though I have not had this issue in any car including my Elise and AW11.

[@StefABtv]

I’m 6.1 mate :)

[@thargor6750]

If I keep watching the videos one day I will have one!!

[@StefABtv]

Haha do it :)

[@thargor6750]

Trigger pulled........ you sold your car!! no matter, one came up. Im getting it Sunday!

[@BobbyDazzler888]

Did you replace it with the same factory sensor?

[@StefABtv]

Yep :)

[@joshuaneve280]

About to order a 595c comp.. any idea why nobody seems to get the “c”?

[@StefABtv]

I just dont think we have the weather here in the UK to merit the C although this summer has been a different story haha. lots of european cars are the verts :)

[@joshuaneve280]

Stef ABtv good point. I don’t mind the extra ££ and not using it as much. Just wondering if there was some mental disadvantage to having it or anything. I like the look of the black roof too haha

[@misterruggles9736]

Did you buy this new or used, and what was the cost?

[@StefABtv]

Bought it used 2 years ago for £11k

[@stautomotive7500]

Is it the top or the bottom sensor? i have the same problem but i can’t figure it out. I did replace the oxygen sensor at the bottom of the down pipe but i didn’t replace the top one.

[@StefABtv]

It was the top sensor for me mate

[@VUO4E]

start saving for the next lambda sensor. lol

[@user-zs4gd2vb9g]

Beautiful

[@altgene8372]

Oh please! The Lambda sensor should of been the first port of call. A case of over looking the obvious, could of halved this video.

[@StefABtv]

Could have saved me time too 👍🏻

[@oldschoolpassion7092]

hi stef , how many millimeters are the spacers?

[@StefABtv]

16mm front 20mm rear

[@oldschoolpassion7092]

Stef ABtv thanks bro :)

[@theresonly1truth138]

Is it the lambda sensor the oxygen sensor?

[@StefABtv]

Yep

[@JVC0313]

Can get that rear spoiler here America

[@StefABtv]

Yep RRM

[@w8wod430]

have you got spacers on your wheels? if so what mm

[@RATSBLATS]

kzbin.info/www/bejne/pnqwmYx6jr-dla8

[@w8wod430]

AudiA4TQ thank you

[@RATSBLATS]

ReWd WoD You're welcome mate, I know pretty much all Stef's videos, so I knew which one to look for 😉

[@w8wod430]

AudiA4TQ absolute legend, thanks again

[@DB-nm4hf]

is it running 250hp with stock internals?

[@boomerdiorama]

Yeah. Stay away from buying a "turbo" car like this with "hard passes" on the engine. Guaranteed the stock internals have accrued micro damage to crank bearings and valve seats due to extreme cam slap.

[@jamesjack6769]

I've heard of piston slap but never cam slap.

[@AnonymousCOD2024]

The fact anyone ever bought a Fiat..............

[@mihaialexns]

Than go buy GTI crap from VW.
