i love my 335d (touring) so much. such a great car.

[@mandycowey7635]

Bought a 66 plate 335d last year. Absolutely love it, puts a smile on my face everytime I drive it. 2 things that are a little disappointing, the brakes best described as adequate and the suspension a little on the soft side when you start to push it. Had a stage one remap a d put a bigger intercooler on to keep the temps safe. Now 420BHP with 754Nm torque. Forgot to mention because the torque went over the max limit, had the box mapped to. What can I say..... whoosh sex on wheels

What manufacturer and model is the wheel in the showroom on this video?

[@thefiestaguy8831]

I have one of these, 67 plate 335D X Drive. The original pads were BMW OEM and I felt they were quite spongey... I replaced front and rear discs and pads and opted for EBC Yellowstuff. My word they don't half squeak a lot and the braking feels a bit better but I still think the brakes are not brilliant in this car. The first few cm of travel in the brake pedal does nothing and even the initial bite after is only "medium" or "Average" at best. You really have to mash your foot down hard to get proper heavy braking. Before anyone says "Get the brake fluid changed" I service my car well (probably too much). It had an oil change 2 months after ownership, in April 2023 it had a full service done, May 2023 the discs and pads were all changed as above and in August 2023 it had a major service (every 2 years or 24,000 miles), the brake fluid has been changed and it's made no difference. If a big brake kit wasn't £3,000+ I'd be opting for that. But for 3k I could literally retrofit heated seats, reverse camera and change the Michelin runflats to standard Michelin PS4's on all four corners and still have 1k change left.

[@hamesto6992]

Really recommend switching to non-runflats at some point. I just switched last week to regular tyres and it's made a huge difference to comfort - really soaks up all the small bumps and undulations!

[@thefiestaguy8831]

@@hamesto6992 I would do but the problem I find is that a lot of the roads I drive on are utterly appalling. The other issue I have is that often I'm miles from home, so if I did get a puncture sitting at the roadside faffing about with a puncture repair kit is a lot more hassle than just continuing to drive but slowly. I once left the house for work at 6AM, noticed I had a flat rear runflat tyre. I drove to work on it (6 miles), back home again also 6 miles, then to work again the next day AND from work about 5 miles to the tyre garage to have replacements fitted. What standard tyre would get you 23 miles with little to no air in it? I've had standard tyres before and had punctures and every time had to stop within a mile because it's totally deflated. The other issue I have is that I can't afford to just simply lay out £1k in one go for decent summer tyres, and the front and rears seem to wear at different levels so need replacing at different times. If I replaced the RFT's for summer tyres when the fronts were worn I'd still have perhaps 4-5mm of tread left on the rear RFTs.

[@thefiestaguy8831]

@juanfranciscourrealeon1295 Thanks for your reply. I did look at this some months back when someone had one fitted to their car - but they stated it didn't really make much of a difference. I'll certainly revisit/reconsider this idea as it's not massively expensive to do.

[@thefiestaguy8831]

@juanfranciscourrealeon1295 Ordered some steel brake lines for £69.99 for all 4. Going to get them fitted in the next few weeks as the brakes is not something I do myself.

[@thefiestaguy8831]

​@juanfranciscourrealeon1295 I have 225 45 R18 on the front and 255 40 R18 on the rear. I want to change them to 19" rims as they look a lot better. I understand as mine is the X Drive variant the system will only accept a tolerance of around 2% in terms of wheel difference. I quite like the BMW 704 rims design but unfortunately they are only available in 19 inch or larger. By the sound of it you changed your tyre rim size also... I'm guessing without any problems?

335d xdrive mapped with no intercooler mods should be good for 370 to 380 hp. is it worth spending another 1.5k on an intercooler upgrade to gain minimal more hp of around (15/20). XHP transmission map is the way to go £370 with license and 3 maps .stage 1 mundane cruising mode , stage 2 great on normal roads n motorway in D and S mode, stage 3 fantastic for B roads in normal D mode S mode is mental best for fast B roads or track no good on motorway or cruising.UNICORN just outside of Manchester have a calibrated 4 wheel rolling road they concentrate solely on live mapping .

[@jimb12312]

Upgrading the intercooler is not always about boosting max HP. It helps to maintain power on the track. Reduces heat soak. On a dyno run you might get say 370HP but try repeating that dyno run 10 times in a row and see how the power drops with a small intercooler getting heat soaked.

[@paulwhiteley2957]

Well here's an unexpected update, the car spewed its guts and dropped a rod bearing at 103k and destroyed the engine which had full service history !! they reckon bmw set the tolerance too tight which starves the journals of oil stretch bolts stretch release the bearing cup and as they say the resr is history or a 10k rebuild !! Be warned when you do the gear box oil and filter change do the bearings too 1k cost is better than 10k rebuild.

@@paulwhiteley2957 I hope I don't have the same issue. I got a 335D remapped to 330HP. In New Zealand all the tuners do mild conservative boosts on stock hardware. Not like crazy Euros pushing 370 HP on stock. I'll be upgrading to Wagner Evo2 Comp intercooler next week before pushing much further. As far as I know, best prevention for rod bearing failure is simply let the engine warm up and change oil frequently.

Cheers fella you've helped me make my mind up. 335 it is for my next motor!

[@thefiestaguy8831]

They are honestly great cars. I have 67 reg one in mineral grey. No heated seats or reverse camera but it has got parking sensors and standard cruise control (not the "Adaptive" cruise control). Was supposed to be around £20k and at the time I bought it I paid £18,300 including a 3 year warranty. 67 reg with 59,000 miles on it bought in December 2022, decent price to be fair, it was the only one advertised in the entire country that I found at that price for the age and mileage. Since then I've fitted the larger pro-nav 8.8 inch screen which I fitted and coded myself using Bimmercode, to replace the original 6.6 inch non-touchscreen which looks awful. For a big 3 litre diesel saloon it honestly goes like sh*t off a shovel when you want it to. I've left an AMG A45 for dead at a set of lights just before a large roundabout in Brighton even in the damp. I was away from the lights, onto the roundabout and at my exit before the A45 had even got fully onto the roundabout. When you want to relax and cruise around however it acts just like a normal comfortable cruiser, and I get easily 35-39mph without even trying and driving it like it should be driven a lot of the time. I've heard people state they can get 40-50mpg in these but I've never seen 50mpg. Best I got was about 45-46mpg on a long run on the M20 which was about 60-70 miles at 70mph with cruise control on. These things honestly give performance cars a serious run for their money. It pulls quicker than an M140i and M3 but slowly the 140i and the M3 will claw back the advantage and come past, the 335D is one of if not the quickest car off the line.

[@thefiestaguy8831]

@@kevmcd8603 I looked at the Golf R, although I prefer bigger cars. The only thing I can't stand is what I'd describe as a tacky interior, the Golf R has almost like picnic style chequered stitching on some of the cloth seat variants which just looks tacky. The steering wheel to me also looks and feels "low rent" as does the interior. For a car which costs £25,000-£35,000 it simply isn't good enough to me. I drove a Golf GTI rental from Zipcar on a few occasions and the interior just wasn't good enough for the price, when you compare it to other German brands. The performance is incredible, I saw a Golf R Fly past me a few years back when I had a Focus ST. I have the saloon version of the 335D and for me it's the perfect balance of space, comfort, efficiency and performance, rapid performance but isn't overly harsh, bouncy or uncomfortable, decent efficiency too with up to 50mpg from a 3 litre engine is quite impressive. I drive in a spirited manner most of the time and I can still achieve between 35 and 39mpg 99% of the time.

You should be getting more power. 360bhp is standard for a stage 1 tune. It’s looks like the guy used a standard flash tune that won’t utilise the upgraded intercooler. Unlike a petrol engine this needs to be specifically tuned in. A proper dyno tune will sort this and hit slider to 400bhp. Then you’ll be kicking his M2 any day🤣

[@Phil-Cooper]

Hi Ross, we can make more, customer wanted it kept as it was, the intercooler was a complimentary hardware addition for the summer months. Guy does over 1k miles a week so wasnt interested in using more fuel (fuel = power) sometimes tuning isn't all about the numbers.

Has anyone upgraded the timing chain before all these mods? Chains are notoriously week on these cars!

[@mandycowey7635]

I believe that was prior to the pre F series models

[@thefiestaguy8831]

Prior to 2015 the timing chains had design flaws with the plastic guide rails, and were prone to coming off or snapping. Since then apparently BMW claim they are "fit for the life of the car" which I don't buy along with a lot of people. My 335D is a 67 reg and has done 79,800 miles and I plan to start saving up for a replacement timing chain, because I imagine my warranty will claim it's a "Wear and tear" item and won't cover it. The total cost varies but the lowest quote I had was £1,860 and the highest I've seen was £2,600, unfortunately as the timing chain is only accessible by removing the entire engine it's a lot of labour hours hence the high price. I've seen on plenty of BMW forums people with older 335d's than mine stating they're over 100k miles and still going strong, saw one person state he was at 140k still on the original chain on a 15 plate 335d. I plan to get mine changed no later than 100-110k mark. If it snaps you're in big trouble and you can easily spend 5,000+ on repairing the engine.

[@Thuds593]

@@thefiestaguy8831you sound paranoid

@@Thuds593 With good reason. The timing chain replacement is around £2,600. However if it snaps at any real speed, it causes serious damage to the engine and may require a complete engine rebuild or replacement.

[@Bond2025]

At 6:00 he is talking rubbish, you will not gain ANY power without injecting more fuel in a diesel and by injecting more fuel you WILL change the emissions. The secret is to stop just before you get loads of smoke as that show unused fuel in the combustion process. The excess fuel burns off in the exhaust maniold and turbo and blocks the DPF and CAT up much faster. When you do a regeneration it causes havoc as the car is already injecting more fule, so when the ECU does this during a forced regen it just pumps diesel down the exhaust and a lot of it ends up in the engine oil causing premature failure. There is more to tuning a car than copying files on to it or getting ripped off with one of those £10 voltage multipliers that sells as a tuning box for £500. If you inject MORE FUEL you will get LESS MPG ! Can't wait to see if it's been crashed!
