Hi There, Mine had a similar problem a while back and it turned out to be a blocked fuel filter. As soon as i changed it the car went like a rocket again. Hope this helps.

Hi again, I have changed my temp sensor and the temp guage now behaves itself. When the car is cold, regardless of if it is summer or winter, it is a pig to get going (worse in winter though for obvious reasons!) when it does cough into life it spews white diesel smoke out the back and between 1000 & 2000 rpm it has a real misfire so you have to rev it to pull away without stalling. I intermitantly hear the relay clicking, but not all the time from cold. When the problem first started i changed the glow plugs, this also had no effect. Should i start by changing the relay? or should i get someone to run a fault scan? If it is a fault in the ecu can it be fixed? or does it mean a new ecu? If so how much are they? Sorry so many questions but i want to solve this problem! its driving me crazy! apart from that i cannot fault the car, it has been great! racked up over 50k in the last 18 months no problem! Cheers

Sorry to pull the spotlight off rob but after all it is my original post!! I have changed my temp sensor to the green cap type and it is still the same. Do i need to disconnect the battery to reset the ECU after fitting the sensor? Temp guage now behaving itself, but still runs like a bag of poo, and won't start very easily on cold mornings! Has anyone in Newcastle area got vag com that could help me out!!!!!!!!!!!! Help Please !!!!!!!!!!!!!!!!!!!!!!!!

Thanks for the reply. Is the glow plug control box the same as the relay? or is that something totally different? Could Vag com software tell me if it is faulty? If so, is there anyone with this software near Newcastle upon tyne? If it is the control box, is it expensive to renew? Cheers

Hi All, I have been a starting problem with my 2000, 1.9tdi (90hp) Octavia for nearly a year now. So far i have replaced all 4 glow plugs, and yesterday i replaced the coolant temp sensor (green cap type). Nothing has cured my problem. Any suggestions please? I am now running out of patience. The glow plug light in the car is coming on but doesn't seem to stay lit for very long on a cold morning, and sometimes on a hot day the glow plug light stays lit for ages and she fires up easily! Once she gets running on a morning there is a noticable misfire at around 1500 rpm, very lumpy! You can hear the glow plug relay clicking in and out on acceleration so i didn't suspect this, or could it still be at fault?? Also she has recently become abit smoky on regular driving. She has 100k on the clock and regularly gets blasted up and down the A1. Please help me!!!!

when was the last time you changed your diesel filter? I had a very similar problem with my 1.9tdi octy last week, turns out it was a clogged fuel filter that was restricting fuel flow and not letting the turbo kick in, the most the car would do was 60 tops, and it took ages to get there!! I changed the fuel and air filter and the car now runs like a rocket!!

My problem is now sotred!!!! It turns out that the fuel filter was blocked, after a new fuel and air filter the car now flies along!!!!

Thanx, will try that at some point today. The car feels a little better this morning, but still not on full form. I think i am going to look at making a mod so that water spray will not enter the air box, i notice that skoda have conveniently placed this facing forward in the middle of the grille!!

I have just done a long journey in driving rain and road spray. On my way back my 2000 octavia 1.9 tdi (90hp) started to become a bit hesitant, if i put my foot down at 80, she would not budge then surge then hesitate again, after my run i slowed onto backroads and the car seemed to be running great. i returned 20 mins later and drove it for about 5 miles and it drove like crap!! i noticed a distinct lack of turbo whine and a reluctancy to accelerate, with the clutch dipped the car revs fine, but with no turbo whine. When i got back home i looked into the airfilter box to find the airfilter soaked and splashes of water in and around the intake to the MAF. Has anyone experiened this before? Does all return to normal once dried out? Please help!!!!!!!!!
