Just moved from 140bhp to 170bhp Sport-what are the differences?

[jagr]

Any ideas chaps?

First step is call VW to ask whether or not the injectors have been changed.
Do you have access to VCDS? if so scan the car for errors.

[manity]

had this with mine a while back i used vcds to force a regen and it has been fine since.

UPDATE

Spoke to VW dealer and injector recall and valve drive recalls were done in Feb this year.

Spoke to last owner who had spent a fortune at his local garage replacing sensors and all sort of parts trying to sort the DPF light issue out. He said it would stay off for 50 miles or so and then come on again. Final straw was the garage saying it needed new DPF which was fitted and problem still persists. The garage told him they had got a 'specialist' to visit them about this issue and the 'specialist' said all the car needs is a software update at the VW dealer. I just don't want to spend money changing brand new parts like the last owner did.

Our workshop has a version of VCDS but i am not sure how much they use it.

The invoice from the DPF work carried out at a reputable garage states 'DPF regen burn not possible'

The problem sounds like something the garage has missed, something simple maybe?

We have had issues with Nissan DPF filters and the force regen (driving at 3000rpm on Mway) never used to work.

forced regen can only be done through vcds must be run at between 1500 and 2500 until the % drops to 0. i had the same problem as you have and tried a long trip at about 3000 rev it didnt work and blew the Exhaust Pressure Sensor g450 which put me in limp home mode. i replaced the sensor £50 and done the forced regen and the % dropped to zero and fault light disappeared have a read of my thread.

How long did you run for in 'regen mode' before the exhaust pressure sensor? Would I know if I had blown it?I did a read on my scanner and there is only one fault code which is the particulate filter code. I have taken a positive view that at least the car has new parts fitted which should rule out some causes of the problem. I am taking the car to a garage owned by someone I sometimes buy cars for. He is a VAG specialist with dealer level software, he bought the latest equipment from a VW franchise in Canada which folded. When I spoke to the last owner of the Passat he had been told by the garage that fitted all the parts that the car now just required a software update. Whatever is needed I know that my guy can do it, he mentioned ecu updates etc if needed.The last owner kept saying how much money he pumped into the car trying to fix it. He traded it in for a petrol vehicle and said he would never buy diesel again.

I told you it would be a pile of 5h1t, didn't think it would be that quick, but bargain auction prices always mean unfixable problems included, now do the best thing and get the DPF taken out and re-mapped, sell the DPF on and straight after sell the car on, this is probably the 405 of the 21st century this model, I'm so glad I bought a 140 non dpf one, and this one is bad enough, I can't wait to get rid of and go back to a VX, cars nice, company isn't.

Just shy of 20K covered in my BMR Passat in 18 months now, no DPF light but I do occasionally get the car doing odd things (Like hesitation initially when accelerating, or a few drops in RPM when sitting at 20-30 steady speeds) so I'm hoping that I don't start getting these problems. I had my injectors replaced about 2K ago - no issues really to report on the car - it's got 62K on the clock now.

What about the DPF removal process? If you like the car and this is the only downside, is it worth removing? It's something I've always thought I'd do if the DPF ever needed replaced.

Move it on? We buy cars, fix them and retail them. I don't know how to do anything else. I can fully understand a civillian getting upset, panicing and selling a car with problems, no other car to use, don't know who to take it to etc. If cars did not break down our company would not have been trading 81 years. I could take the light off and put it back in BCA Friday, watch someone else buy it, fix it and retail'em. I can point to nearly any car and list expensive 'common' faults that particular vehicle can suffer from. Sometimes i go to pick cars up from the block and at the turn of the key the engine lets go. Sulk then commences for an hour before we buy recon engine and sort it out. My family were Rover dealers for over 50 years so as i said, we don't know anything else than to fix 'em.

Thats fair enough Phil, but these are money pits I'm afraid, like I said nice car, lousy company, if the reliability was as good as the looks, and the costs as low as the suspension then it would be the one to have, sadly it isn't and VAG are on a progressive downward slope since they stopped making the B5.5,

Mine eats oil, misfires when cold on a hot day, has some sort of deep rumble going on that gets me in one ear after a while, if I took it in I'd get the old no fault and here's your bill sir routine, turbo wails and has been since 40k, I'm sorry but this is what I expect if I bought a cheap Kia not a very expensive "premium brand" car from the dealer network, which I also think stinks at sales level, if it gets me though one more year I can say I had my money out of it and then it's bye bye VAG, all the speedo's are out so it makes the car look more economic than it actually is, VAG will play any trick to get the punter into believing he got a good deal,

Even the pricing is bad,

11 plate Insignia mid spec 15k otc £11500

11 plate Passat mid spec 15k otc £16000


px after 5 yrs

11 plate Insignia £3500

11 plate Passat £5000


£4.5k more to buy, £1.5k more in px

And the Insignia is a mile in front in the looks department, you could say the B6 vs the Vectra C was a no contest, but not now,

Anyway Phil, good luck with it mate, if I were you I'd shift asap tbh, and at BCA rather than retail it if you value repeat custom, which if I read you right, you do.
