Many of the 170 are DPF equipped. If you are considering re-mapping, DPF cars are best avoided.
What is DPF?

I have an A4 2.0 TDI which was 140, after having it remapped its now at 180 (give or take a few) and I would thoroughly recommend it. It's like a different car. My friend has also has his 1.8T done and the performance from that is unbelievable. Let me know if you want the guys details of who did the remap, I'd highly recommend him
Thank you for the offer I'll definately take you up on the offer when the time is right. Much appreciated. It seems that the way forward with these turbocharged VAG units is chipping them! I'm suprised more people dont chip their cars
Regarding the post asking which engine I'm referring to I dont know the engines codes but they're the latest engines available if that helps.

Shame the salesman doesn't know the correct procedure to force a DPF regeneration though!!!!!
Which is? We've just bought an 08 plate Leon Tdi FR with the 170ps engine so it'd be good to know what problems there may be ahead and how best to avoid them.There are a lot of issues with sensors on the Skoda Octavia 170 bhp TDI's which result in the dpf light coming on. Some faults allow a regen, some don't. Plenty of info on Briskoda.net, I'm not sure if the Seat engines are exactly the same in terms of mapping, sensors, etc.

I've heard the 170 tdi's are very laggy turbo wise... i'm sure a remapped 140 is probly the way to go?
We had a B7 A4 Avant with the 2.0 170 TDi S-Line (6-spd manual) for 6 months and the lag was horrible. It was genuinely unpleasant to drive. However, I've driven a MkV Golf GT Sport with the 2.0 TDi in 170 form (albeit with DSG) and it was much better.PWE said:

Our 170 PD Octavia VRS was laggy , power was all or nothing but there is a fix for an ongoing sensor fault which caused a light to come on and the car was remapped by the dealer (remap not performance map) , the result of it is a different car to drive , smooth and progressive so much so i've ordered the 170CR Superb FWIW we have never had problems with the DPF in 42000 miles on out Octy
Just to back track a bit. 170 (125kW) engine does have different (larger) turbo and exhaust manifold, and different injectors, although they are visually the same. There is more lag than the smaller turbo, but considerably more punch once its spinning, I've driven lots of each and dont find the lag a problem at all.
The issues with DPF all come from how you drive the car. I have a customer who does 7 miles across town at rush our twice a day. He had to back his car as the DPF light is on every other week and he doesnt have time to do a regeneration drive. Just to prove a point we lent him 2 different cars and the same "fault" occured. This isnt really a problem with common rail engines just the PD engine with DPF and most people have no trouble at all. But the trouble is usually the way the car is driven rather than the sensors and the software which get changed as a matter of course. Said customer now has a common rail engined A4 and I havnt seen him since.
There are lots of myths about regeneration, constant rpm is far far better than going for a thrash. I tend to do arround 50mph is 3rd gear, or what ever gives me 3500rpm constantly for 10mins. In fact going for a thrash, or an old fashioned clear out is actually almost as bad as pottering in trafic.

Currently have the 170ps in my 2007 A4 S-line, 45k miles and the DPF light has lit once. I do alot of motorway miles / A-roads ie at least 60+
I think tame technician has hit the nail on the head, the style of driving dictates the problems, rightly or wrongly.
You could save a bit of cash, opt for the 140ps and remap it at a cost of circa £400.
If you opt for the bluefin from Superchips it's a DIY effort and can be removed and returned to the standard map for servicing at a stealer.

The fact that a regular 7 mile rush hour drive causes a problem with the DPF is to my mind a design fault and it is not just happening on rush hour traffic, as a mate was stranded in Inverness with a faulty DPF in his 170bhp VRS after a drive from Southern England, surely enough of a drive to burn of any particulates and if isn't it certainly should be.The issues with DPF all come from how you drive the car.

I might agree with you. But if a car does somthing and other cars like for like dont, then its faulty. If all the cars do the same thing, then its a characteristic. No one wanted to put DPF's on cars the emissions laws dictated it. I dont think DPF's were designed for the old PD engines and only for Common rail, but at the time of the emissions law change, the common rail engines weren't in the cars yet.
Constant RPM is the thing, even on the motorway if your flat out then brake for some numpty do 65 in lane 3, move him over then flat out again till the next one, you could do 200 miles and not clear it at all.
The pressure sensors for the DPF do go wrong, and there is improved software too. Sound like the car you speak of could do with a new sensor and the latest software then customer to try and report. If it still does it, its the driver.

Had my 140bhp Passat remapped last night, has made a massive difference, especially when overtaking on steep hills. It doesn't seem to run out of steam as quickly as it used to. Well worth it.
Could I ask who did it for you and how much did it cost? Also, what has the impact on fuel economy been?bd02 said:
