!!! Common Issues !!!

[Timmy0607]

Hi Guys.

Ive own german cars for a while now but this is my first scirocco, I have just recently purchased a 2010 plate 2.0l tdi, 170bhp model it has 85k on the clock and i am wanting toi know what are the most common issues to look out far or waht to expect to look for as the milage increases.

If you can let me know i can pre-plan in advance to stop these from happening .

cheers

Hi,

I too am new to these but judgin by normal standards front and p bushes arb links track rod ends etc. top mounts no idea about shocks on these to be honest.

Depends if you maintain by necessity or choice as frankly suspension heavily falls under that mind set.

Engine parts turbos etc greatly depend on their care from previous owners.

Hi,

The car will soon be on air suspension :-) so the top mounts ect should be changed at the same time (I think), im not sure what air suspension actualy will take away, would this remove the drop links compleatly as this will interfear with the car going in to slam mode :-s and also will the ARB (anti roll bar) be removed as there will no longer be a requirement for this.

So if thsi is the case then i can rule out - ARB, ARB Bushes, Top mounts.

The car has only had one owner since new, and it has been service everytime at vw with long life oil ect, im looking at removeing the EGR and EGR cooler as this is a car killer, i did this on my MK5 golf tdi and it made such a differance im also only running on shell diesel as i have been told that the supermarket fuel is full of extra adatives :-s and at winter they add even more :-s.

Hopefully once the EGR is removed and replaced with a streight thought and blocked off at the manifold i wil then be removeing the DPF as this is also a car killer, they are supose to regenerate but never do and thsi has a hugh impact on the car and the performance. Only down side is taht after all thsi i wil then need to get the car mapped, with then you are at risk of the DMF (duel mass flywheel) judder - but we will cross that bridge when it comes.

Are there any outher common issues to look for, any engine bay pipes (pressure pipes) that are common to disitergrate, or any o rings that may need to be replaced such at intercooler pipes ect.

Need to be careful with the DPF as it will fail the MOT without one under new rules as if fitted as original it must remain. Could try to blast the inside away and keep the body!!

Yes - removing a DPF is a strict no, no. It is there for a purpose.

The guys that are going to do it just open it up and take all the insides out :-). but not sure if the sensor woill pick this up as a fault and after this will need to be mapped out

[skippy]

I'm afraid I don't agree with removing the DPF, could leave yourself open for faults and diesels are more polluting anyway (in terms of particulates). Big MOT fail.

I had this removed on my MK5 golf 1.9 tdi this had a streigh though exhaust system and car ran a lot smother for it. my mate also had the same on his mk5 gt tdi. also TDI`s dont get MOT on there emisions they going though a smoke analyst test, both passted there MOT`s (this is befour the new law came in) but even then the test was clear and passted :-). So with the new laws in place the guys taht orignaly removed them now offer a servcie to just remove all the insides and then re-installe the dummy DPF, so it will be the same as a streigh though but will pass MOT as it still on the car. The only faults that this may bring up is the engine light as it did the smae on the MK5 golf and the only way to over-ride this is to fool the ecu and this then removes the light.

MOT laws are getting a lot stricter now, but there is always ways around them. You will fail now if you have any lights on the dash esp ect, im just thinking of ways to get the car to run better rather then chocking itself hence the EGR and EGR cooler removel and DPF.

On a differant note - Has any one camber the rear of there scirocco, I beleve all or most german cars are the same. You have the orignal camber bolt and by turning the washer you can gain up to 2.5 degrees camber. Has any one done this??????

I owned a Golf TDI 2010, was a big mistake, soon after had problems with the DPF, car juddered, ECU took over and tries to perform active regen, that failed, DPF light came, took to garage twice for manual regen, same problem occurred soon after. Basically warranty does not cover DPF, so I had enough of it. Could possibly have been last owners driving style possibly just doing town driving which is not really ideal, these cars love being driven long distances etc...

Anyway, decided to get a petrol car earlier this year and went with a 1.4 Scirocco, just shy of 3 years old, unfortunately started with bad luck (again!), failed fuel flap actuator on first week, then the week after the rear spring coil snapped, luckily the car was under warranty and it was all fixed. After all that, thankfully al has been OK! Car has now done 34,500 miles in total.

When you owned your TDI, did you have the DPF removed or not. with the DPF it is constantly at 25% full, this then inceases to i think 35% and then tries to do an active regen but if this fails your car will reset and try again 3 times, if after the 3rd time if fails again then the regen re-sets to 65% and then tries an active regen again for 3 times if they fail. Once this fails this means taht your DPF is full and will not allow for any more which is when you need to replce it (but this will only happen again) or remove it compleatly but again due to new MOT laws you cant so the next step is to take the insides out and have a blanck shell. you will then need to have the car mapped to fool teh ecu in to thinkin it is still there.

Ive had petrol cars in the past think the best few ive had was my MK4 golf gti :-) and the Audi TT MK1 :-) but after some modifications the Audi took £20.00 per day for a 30mile run so this was not a good idea at all hahahah. the MK4 golf however was still thirsty but not as much and was a great car to own.

When i went diesel to the MK5 golf tdi i though i would not like it but it soon changed my mind and now i will never go back to a petrol again :-)

I believe from February 2014 they introduced the mandatory DPF for MOT purposes, but by then I decided to get rid of it. With mine I didn't bother removing it, think the filter was knackered and I believe they are not cheap!

I did manage to keep the light off, but had to change my driving style - driving the DSG in semi automatic mode and using up to 6th gear on the motor way to keep the revs up to a decent level.

It was one of those things - I think VW's engines are generally very good, getting more efficient as time goes by, the gearboxes are very good as well. The Golf always felt and gave a solid ''ride''. The new Audi TT MK3 looks nice, not cheap, wouldn't mind one of those!
