Evening folks,

My first couple of weeks of Skoda ownership are not going well, the very heavy rain today has brought misery to the north east and my Octavia 2.0TDI.

I am sitting at the side of the road after being forced to stop in some standing water, as the car in front (which was a good bit in front) stalled. Everything seemed ok for a few miles until the car started missing, then it got worse and the emissions light and engine light came on, now sitting waiting on the AA.

The car will start and idle ok, but when the throttle is pressed it stutters like hell and dies shortly afterwards.

Is letting it dry out a bit and things being ok too much to hope for ?

how high was this standing water?

if it was high im guessing possiable water might have been sucked up the exhust pipe.

AA should be able to find out the issue quickly once they see it

Sounds like the water was quite high. In such circumstances either avoid the water, or DONT stop! I've driven in water half way up the door before, and keeping moving meant I didnt stop where others did.

Get it home and drop the bottom intercooler pipe off and drain the water from the intercooler. You'll probably find at the moment, the car will start and run fine on tickover but when the revs pick up you're pulling flood water through the air intake and through the intercooler thats causing the water to enter the engine.

Drain intercoler, new air filter and hopefully you're ok.

HTH

keep the revs up high in the water, my car it will leak through the door seal on the passenger side so i know if its too high lol hope you get it sorted.

Yup, I'd guess water sitting in the filter/pipework is probably getting sucked up when you try to accelerate. Sounds like you might have had a lucky escape. This is exactly why you should always wait for the preceding vehicle to exit the water before you enter it!

On the 2.0 TDI the air filter has a slat system that should allow water to drain out on the intake side of things, before it passes through the filter.

I'd check the intercooler isn't full of water and pop a new air filter in there before it hits the dealer myself.

Thanks for all the replies eveyone.

The AA guy (or the third party rep they sent) reckoned that there was water in the

exhaust system, as the emmissions light was on.

To be honest, he didn't do anything fancy, but it seemed to clear and got going ok again for 10 miles or so before problems occured again. He was getting implausable signal errors reading the ECU, so he suspected they were a bit wet.

Since the rain went off I sat with the engine running for 20mins then gave it another go. Car ran perfectly fine after then, pulls ok, MPG is spot on and no misses anywhere and no warning lights !

I did think of changing the air filter, but is it still an idea to see if the intercooler needs drained ? If so, is it easily accessible ? Done around 400 problem free miles since the visit through water.

A lesson learnt. If someone gets just about all the way through standing water, wait until they are clear it, the guys car died just as he was exiting it, which forced me to stop ! Water wasn't that deep really, well not half way up the door like one post said.

Thanks again !
