Following on from my 9 days electric windows repair, it's back to the dealers first thing in the morning.

On the way home on Friday I had thought that something just felt a little different. It's only about 2 miles/5 mins home but when I parked up it was already up to normal temperature. When I took the key out the cooling fans were racing and didn't go off until after about 5 mins after I switch off and on a couple of times.

Yesterday it felt like the gearbox was struggling somehow. It was taking longer than usual to change up into 4/5/6. It wasn't going into 4 until well into the 30s no matter how gentle I was and even 40 wasn't seeing 5.

This morning the exhaust thing light is on and after a quick read here I went back to check and sure enough its in limp mode and 2500 max rpm.

Worried. :'(

It could all be dodgy earth somewhere?

It all points to the dreaded DPF problem I'm afraid.

Your Friday symptoms sound like you did too short a run and a regeneration did not complete, why if only one trip of about 2 miles I do not understand, just because the engine is at normal running temperature does not mean it will regenerate, you need a considerable temperature in the DPF. At times I have had to make many short runs but never known a regeneration taking place or the cooling fans operating on my first MkII 170 CR which was DSG. My new Combi 170 is manual and also not had cooling fans running after a run. Have the dealer do a forced regenration and check the sensors, these are the main cause of suspected DPF trouble.

Also with the car lurking around the dealers workshop for that length of time it would have been started and stopped several times without warming up to make room for other vehicles.

Totally agree with this, worked at one dealer once where all the better for sale vehicles were taken in from the forecourt and garaged in the workshop overnight, then out again next morning, every now and then some were given a run of about 14 miles.

My point about normal running temperature was that I don't think it should have warmed up quite so quickly, almost as if it had warmed up because the engine had been fighting against some sort of retardation.

Anyway, just waiting for Skoda assist to attend as the dealer said I'd be able to get a hire car if they had to take it away.

Ps, would a symptom of the DPF problem be a struggling engine?

Well, Skoda assist just left. Impressive, really seemed to know his stuff. Straight away on hearing symptoms he went to dpf. Said its either clogged due to short trips, and unable to regenerate, or faulty sensor.

Hooked up to laptop which showed 174mg (of whatever ) even at idle, when it should have shown only a few.

He replaced the sensor and retested, when it showed 3mg estimated and 0mg actual. He then performed a forced regeneration (i watched it take over and do all the revving up and stuff).

He also explained that the reluctance to change up gear was it trying to heat up the exhaust to the temp needed to regenerate, and the fans going is all linked.

Hopefully all's well now.

Pleased to hear your esults, and Skoda Assist were on the ball.

I am a retired Motor Vehicle Technician, and have known DPF's still going at over 130,000 miles, even when driven in an enrecomended manner. I am sure that most of the claimed DPF problems are caused by faulty sensors and incorrect diagnosis reading.

PM on the way

Just returned from test drive and pleased to report all back to normal. Changing up at all the correct speeds again and no fans.

Such a relief! Thinking allsorts, dodgy box, siezing engine etc..

Thanks everyone.

PM spectrum? Bill?
