OK; update post read and understood.

I take it, from earlier posts, that you don't want to go the DPF off route quite yet, therefore we have to get you car running sweetly in OE spec.

Totally agree that you should first of all go back to Perfect Touch and get you ECU map reverted to OE spec. They seem like decent and professional enough guys, although I have not heard from them before and they seem not to 'major' on VAG group stuff; no matter.

Next step is to get you DPF cleaned out as that is what appears to be needed, before going back to you dealer if need be. Are you willing to name who?

To get your DPF cleaned out. Here you need to humour me and go with the flow as there are wide ranging and conflicting views on the subject, all I say is from my own experience of running a vRS TDI for 3 1/2 years and 56,000miles that I sold earlier this week and not (fortunately) having a peep of a problem. I cannot assure results either; sorry.

Use Shell V-Power fuel for the next couple of tanks, that will do you 700-800 miles, and also get some Millers Diesel Plus/Sprot4 used at double strength of 100ml per 50 litre tank.

Next step is to do a couple of DPF cleaning runs, if you can't roll these into your usual miles, as previously mentioned drive at a steady 1800 - 2000rpm in 4th or 5th gear for 15 - 20 miles and then try and use this rev/load/speed configuration in your normal routine.

Actually; try this.

1. Get ECU remapped to OE then

2. get Shell V-Power/Miller in your tank and then

3. call Skoda Assistance (the RAC) and say DPF regen keeps happening, don't want to drive car, could they come out? Get the RAC person to hook up his/her diagnostics and then go for a regeneration run with their PC connected.

Make sense? Good luck?

All read and perfectly understood.Would like to add you as a friend so i can inform you off outcome.

Thankyou very much for taking the time to help this really is an excellent site.

Roadhawk, in post #4 you mention that you don't want remove the DPF yet as the car is still under warranty.

However, now you have remapped the car the you have just invalidated the warranty on the DPF. If the dealer detects the remap they will tell you to take a walk with your DPF problems.

You really have 2 options

1. Get the standard map put back on your car and then do the above as Bahnstormer recommendations.

2. Remove the DPF from the car and have the car remapped to suit. You will then have no further DPF problems, your mpg and bhp will also increase.

P.S. I suggest you remove the Dealers name from the above post, as dealers have been known to use these forums.

Excellent advice thanks for the hint. In respect of DPF cant wait to see the back of the thing i just have a few reservations that it is definately whats causing the problem im just surprised the light has only illuminated once indicating the filter cant be that clogged.

Do u think even if its 50% saturated that will be enough to stop the remap being efficient to the extent of 20+ bhp ????

Intend on carrying out Bahnstormers instructions to the letter...

Thanks again

UPDATE ON THE DPF ISSUE

Well carried out Bahnstormers instructions to the letter ref fuel the millers reverting the ecu back to oe settings and skoda assist, after explaining to skoda assist (RAC) the nature of the problem and repeatedly saying need a vag technician you may guess it after a 2 hour wait on the delightful A10 they send a non trained VAG technician with no vag fault diagnostic equipment !!

However the chap was incredibly helpful and called his colleague who would be working the following morning and to expect me calling back in to rebook the job.

Again a fabulously helpful fella turned up and plugged in the trusty VAG 50/52 diagnostic computer went through sequence of checking all fault codes and there was quite a few refering to some additional audio equipment fitted he cleared all faults but one.

Anyway we got into the dpf section of the system and LOW AND BEHOLD 31% soot load nowhere near enough to cause the grief i was getting never the less he was happy to force a regen so of we go once vehicle upto running temperature we switch into regen mode, 50/52 tried 3 times to force the regen over a 60 mile journey we made and the ecu was refusing to do what it was being told to.

This was a new problem to the tech Dpf not blocked but ECU not responding exactly as my mapper found. Next stop Skoda main dealer with Mr VAG amazing the service u get when walking in with one of these fellas !!!!!!!!!!!!!!! Car now booked for monday.

Now me being me cant leave this, vehicle been in twice and they never even picked a single fault up so what chance have i got now

Well now knowing its not a DPF related problem i contact an extremely good electronic diagnostic chap i no now the single fault code that was left has been there since day one as i had a friend who has a cheap hand held diagnostic tool that reads any codes on the ecu i remeber googling the code and it related to a dash pack problem now at this point i dismissed this as an issue mainly as everything functioned perfectly,

How easy to overlook something that seems so irrelevant that has turned out to be quite the reverse.

After a brief chat with the electronics expert and telling him my problem he states "it can only be 1 of 2 things" a faulty ECU or a problem in the CAN GATEWAY located guess where in the dash pack exactly where the initial fault 6 months earlier had been detected.

Bring it down he said were check the config settings.

Now after he checked all settings which appeared normal he run a full fault check Guess what the result was negative no fault found.

Now im feeling very confused VAG saying it has a communication problem and Andy saying nothing wrong. He uses a different VAG system which he states does everything the 50/52 and 54 does and more i think he refered to it as the VCDS system or something like that.

Now the most relevant thing that happened later that night to this story was during the heavy rain we were having i noticed a very strange new occurence with the wipers every time i stopped they went into intermittent mode and as i pulled away they came back full again this had never happened since ownership of the car, Ive since studied the book and read this is a standard feature.

Now what shall i do has the VAG systems cleared something and all is ok or should i go to the dreaded dealer tomorrow. My electrician suggested sticking remap straight back on it and see result before inflicting no brain fitters on it. REALLY NEED SOME ADVICE ON THIS ONE BEFORE TOMORROW.

My you have been busy in the last few days! Taking note of all you say I'll offer these further comments;-

1. At least it would appear that you do not have a blocked DPF; although 30% soot is higher than it ought to be.

2. Yes; Intermittent wipers when stationary is a standard feature.

3. You seem to have cleared some electronic glitches. These may have been the source of your problem.

What to do? I'd suggest this.

I'd keep your appointment with your dealer tomorrow; at least they have been told what the problem is and, you having cleared the ECU glitches, they might well be able to force the DPF regeneration and get your 30% soot down to the 10-15% max that it should be.

After that I'd run the car for a week or so (750 - 1000 miles) to get the benefit of VPower & Millers, see if things settle down and that you have lost the persistent attempts at regeneration.

If all is well after that, then by all means go ahead an get the remap re-installed.

Good luck.
