PD130 1.9TDI ASZ VW VAG - TANDEM PUMP DIESEL LEAK FIXED - NEW SEALS.

In this video i replace the tandem pump seals on my 2002 VW BORA 1.9TDI PD130 ASZ car, this is to rectify a external diesel leak. Hope this video is helpful

[@bonza007]

Thanks for doing this video Cally. I replaced the cam on my engine a few months ago and didn't replace the gasket, so now have to go back and tidy that up. I know which gasket set to get. Cheers.

Seems as much age dependent as mileage , mines only done half the miles but was leaking, but they are all knocking on 20yrs now. The sooner you catch it the better - even a small leak will soften the cooling hoses below the pump - I had to swap 2 of those hoses as they were badly softened by diesel and I didn't want to risk them failing.

[@Jimmy-sc2ib]

lots of great information here about the multiple versions of the pump. I am having problems with my brakes lacking vacuum. No leaks in the vacuum system between pump and booster, hoping the pump could be the culprit.

[@callytech.d2r813]

Good luck, yeah few years ago before this leak the vacuum pipe to the back of the tandem pump had a split in it, my brake pedal was very hard, no power assist whatsoever, replacing the pipe solved it

Thanks for this. Got the same Bora, colour as well.

Autodoc supply different makes/quality. Mines stinking of diesel and I'm right down Cornwall on holidays Hope it doesn't blow suddenly. Good video from fellow biker and vw owner. Thank you.

[@Papasbags]

Cheers for video bro!

Good job cal

[@diogo1966]

The plug on that fuel like is a fuel temperature sensor. Mine is leaking too, hopefully building courage to do it myself.

If you have the no start issue because of diesel, there is a short video here somwhere, explaining to cover the exhaust one or two cranks the unpulg the exhaust and ur diesel engine should start, hope it works to get yall running and how or to a shop. It worked for me it help bleeding out the air or something

[@meeseeksbox6548]

Leak fixed ? I was thinking upgrade to Bosch because I heard that Luk pump leak even after replace seals. Thanks for vid. Regards

[@callytech.d2r813]

Yes it seems to have fixed it

[@paulflynn868]

Hello mate, how long start to finish did it take? Excellent video. Keep up the good work 👍👍

[@callytech.d2r813]

Thanks mate, erm I say it's about an hours job really, but set aside 2hrs for any snags

[@tamasszabo3925]

Does the fuel level indicator drop to zero even though there is fuel in the tank, because of air bubbles in the line or damaged seals?

[@callytech.d2r813]

Personally no I have not had that happen to me. The fuel level is usually a float indicator in the tank, so I don't see how air in the lines could cause this.

[@blobby750]

Thanks, great video. Does this issue throw any DTC?

[@callytech.d2r813]

It did not for me but I could imagine if thr leak was really bad it would be flags by the fuel pressure sensor

[@fraser.d2r]

Great vid. Keep it up. d2R

Thank you random internet person who I dont know..

[@gokhandemir44]

I have same problem with my polo tdi.Diesel leaks in first start from tandem vacuum pump then it stops .My question is it dangerous to drive like that?

[@callytech.d2r813]

@gokhandemir44 I suggest you get it fixed ASAP but if the car runs OK it can't be a significant leak.

[@gokhandemir44]

@@callytech.d2r813 Thx for your answer.Yes car runs without acceleration or brake system problem.And what I see after engine gets 90 degrees this leak stops.

[@OmarAliGtti]

Was your diesel leaking or oil?

[@callytech.d2r813]

It was leaking diesel

Where did you get the seals from please?

Mines leaking oil so would it be the same thing 🤔

If it's coming from the same area it could be, might aswell give it a go seals are cheap and it's not hard

Hi Can bad tandem pump cause bad engine start?

Yes for sure it is needed to help get fuel to the Injectors

@@callytech.d2r813 well i have the car now for 7 months.it drove fine and started every morning i had to replace 1 glowplug . I Am a car mechanic but never we touch a 1.9tdi 98% we work on gasoline cars so you know😆 I was driving and all of the sudden it just went in limpmode or so? Beqause the car felt shocking and it didnt wantted to run so it died with a blinking glowplug light😕 I deleted everything treu obd and it had power again WITH the blinking glowpluglight! BUT after a few Miles it died again and it didnt wanted to start again. Tried the next day Leaving to work Beqause 1 car and it didnt go far till it died again and then it was barely starting, en then NO START anymore… there were no crazy engine sounds oh and the dieselpump in the tank sometime when yiu turn the key you heare it slurping and not its 50/50 with slurping also no start i dont knoe it anymore relay 109 clicks glowplug tested all good. I did the mass from the dynamo to under the battery and go on i hope you can help me

[@shaunpmarshall]

Mine has very little air pressure on the vacuum side ...when I brake it brakes properly but if I brake straight afterwards there's no assistance...my thinking is its not pressurising quick enough...soon see as I'm about to do a full rebuild on the pump

[@callytech.d2r813]

U sure it's not a vac leak? Have you check the vac lines? I would do that before rebuilding or replacing the pump

[@shona5512]

My Mk5 Golf is doing the exact same. I'm in the process of replacing the tandem pump because I have a spare one from a ASZ engine. Did you ever get your issue sorted? If so, what was it?

[@shaunpmarshall]

@@shona5512 I haven't started it yet ..been too busy...a good mate of mine said to change the master cylinder first as he's 100% sure that's the problem...rebuild kits are cheap as cheaps

[@callytech.d2r813]

@@shona5512 yes replacing the seals as did seem to stop the leak, although I am still dealing with an oil leak from the rear main seal
