I don't know if anyone can advise I have a smokey exhaust. I've got a T5 2008 Shuttle (LWB) with the 2.5tdi engine with 145K on the clock. Most of my driving recently (regrettably) is short distance town driving - which I am assuming from reading a lot of the other threads isn't the best way to drive my van on a daily basis...! However, I do plan to buy a small runabout so hopefully this won't be for too long.
I recently had to have my fuel injectors reconditioned as I was unable to get the van through the MOT due to failing the exhaust emission test. Once this was done the MOT was sorted - that was 6 months ago. However, this last couple of weeks I have noticed a lot of white smoke coming out the exhaust again. Its worse when I am stuck in traffic or when I am stationary. The smoke can be quite hot and smells acrid plus it burns the eyes so I don't think its just water vapor. The van drives fine and despite the smokey exhaust there is no change in power when I accelerate although, occasionally the van seems to 'misfire' or something but this doesn't happen very often. Along with many new parts of the last couple of years I have had a new EGR valve plus new glow plugs recently.
When I took the van back to the garage who did my fuel injectors in January they seem to think that the injectors are working fine. However, they noticed that the engine had been re-mapped - which must have been done before I had it as I wasn't aware of this. They also mentioned something about the DPF possibly being an issue and together with remapped engine possibly causing the white smoke. Or is possible the DPF has been bypassed or something? They have recommended I get the engine re-remapped with them and to get this linked up properly with the DPF to see if that might solve the issue other than that it might be a case of having the engine stripped to find the cause.
Question - is it worth paying £150 to have the engine - re/remapped and re-set especially if there are no guarantees that this will solve the problem? Are there any other (less expensive) options I can explore?
Also, can anyone recommend any good local VW mechanics/garages who know about T5's in the Lichfield/Burntwood/Walsall area as I think I would like to get a second opinion.
Any help or advice would be greatly appreciated as this is now becoming a bit of an expensive saga for me!!
