Hi to all skoda owners,

The problem that I am currently having from my MK1 vrs octavia is as follows.

occassionaly and it is very occassionaly the car doesn't fire up first time, when it does start at's as rough as a bag of nails, i then rev the engine to try and get it firing on all four, I get a dirty cloud of smoke from the exhaust, it then ticks over at aprox 2k and then settles down and there is no more trouble until the next random occassion. I haven't taken it to my local garage as they would obviously need to see the fault occur and I never know when that will be niether do i get any warning lights on the dash.

I think that this is iether a problem with my "cat" (I do about 20 miles a day) or perhaps a problem with the cold start system.

has anyone else experienced this problem and do any of you know of a fix.

I look forward to flood of info from you.

Many thanks

Ian

How long have you had the car? Have the coilpacks been replaced? They are doing a free recall at the moment if you take it to a main dealer.

Almost sounds like a seal is failing. Is there oil on your coil packs? What is your MPG like?

Mine has developed a simular problem.

When starting the car from cold its really lumpy and jerky. There's a hissing coming from under the inlet manifold untill the engine is warm. I assume its a split pipe under the manifold.

Had my packs replaced under the recall, just done a T/body clean but still bugging me lol :(

Mine did something similar to this today. Ive only used it for small local runs this week and we had the most horendous rain last nite. Went to start it today and it fired up, chugged, then stalled. It did this twice, then when it did fire up it ran rough for a couple of seconds then all was normal. No smoke, or warning lights and seemed to behave fine after that. Ran around for a bit and stopped and started it a couple of times since and again all is fine.

Really dont know what this is. The car has had the coil pack recall but it was a while ago. Wondering whether it was something to do with the really heavy rain we've had and some damp getting to something???

Off to a friends this evening to get the VCDS on it to check for errors and go from there.

Tried doing a vag com check for fault codes but could not get it to connect to the engine module (see my post in the VCDS section)

Anyone with any more ideas what it could have been?

Could have been damp getting in somewhere. If VAG-Com can't connect to the ECU that's a bit worrying. The ECU is under the scuttle panel, might be worth taking the scuttle covers up and just checking it's not awash with water in there or something.

Just been down to see Andy at CC Tuning and hes managed to connect to it fine (must be a problem with the drivers for the cheap usb lead I borrowed causing mine not to connect). No fault codes registered either and temp sensor working as it should so im thinking maybe damp got in somewhere.

Gonna monitor it and see how it goes.

Hi mate, yes coil packs changed aprox 2k ago

mpg is around 32 at present, no sign of any fluid leaks

Thanks Liam, it starts fine from cold and is not jerky, can't hear any hissing

Thanks to everyone for their input and ideas, I will get it sorted one way or another.

Cheers all
