Anyone remapped their passat b8? Looking for advice

Post by smilie121 » Fri Apr 19, 2019 3:25 pm

Anyone ??

I was set to remap with a mobile tuning guy who Avon Tuning recommended, Edinburgh based but will come to me near Loch Lomond. He had to cancel last minute which is a shame. Impatient as I am I decided to phone some folks in Glasgow and got some new information I didn't get before.

My intention was to map out the EGR aswell as the remap. Various places in the past as well as this guy I had booked all said I should get see 230 to 240bhp factoring in EGR removal (map).

But one place said he won't map out the EGR unless I agree to map out the DPF (no extra charge). It is because it will clog and I will be phoning him in a week and he doesn't want this. Not heard that before. If the EGR is closed off I would imagine more gunk would come through. I wanted to keep the adblue and DPF in place.

Also he said my car could have a manual EGR (vacuum) and an automatic EGR (ECU). If it does he needs to raise the engine to access & blank. The guy was Polish or eastern European so bit hard to understand but has a long history of good reviews on google, facebook etc with tons of video's showing his work. He seems to know his stuff from what I read.

His price was the same as the mobile guy at £275 but an extra £300 if he needs to lift the engine to access the 2nd EGR. He would not give me an appointment to remap unless he sees the car.

Sorry for long post, tried to shorten it.

On VAG the EGR is a prerequisite of dpf regeneration it helps regulate both the pressure and temperature so that's why you can't do just egr .

I would do both..

Environmental particulates and NOx Vs just plain bad for the engine and your pocket .

What i had learned was the the DPF was final say in destroying harmful exhaust poo before the adblue finished it so EGR could be removed with minimal impact. I had watched something before about emissions vs extra mpg with regards to egr being in place or not. Also the fact it clogs up and costs a pretty penny

However it appears i should have done more homework.

So I am now thinking if DPF and EGR is deleted software wise, the car won't pass its MOT with the finger test ???

Its due its first MOT in June or July i think (out at the moment).

Mot has a smoke opacity test according to the VIN sticker manufacturers smoke coefficient value .

My 2003 184K with no cat and one silencer blows a 0.34 fast pass .

Even a sub 2.0L dpf equipped car can cough 2.00 on the first acceleration .

Was I not reading something on here about the tester shoving his finger up and seeing if it came out dirty? The exhaust pipe i mean =)

It's not mot procedure , dpf is just a mot visual and smoke opacity test .

Most dpf can't be seen , even then there's always a blind side for the surgery or even take an end off and some oem immaculate welding .

Is that still the case after they tightened the MOT regs in early 2018 ??

Seem to remember reading no modifications to exhaust allowed ?? I am on my phone still but will look it up again when i get on the laptop - rather than guess
