My car is a Nissan Tiida, 2008. It got flooded 5 weeks ago. Water came in up to the dashboard. It was towed away to a mechanic and I got it back supossedly fixed after 3 weeks. The first problem happened 1 miles away from the garage when the honk and all alarms went off bezerk. I took it back to the garage and it got fixed. They said it was some circuit which cuaght mold or rust or something and got changed. Then I took it to a drive to a city 150 miles away. About 1/2 way on the highway, engine light started to blink, the car lost some power but kept on going, then check engine light stabilized up to destination. In the evening I moved it and check engine light went off by itself. On the return, the same story so I took it to the garage again. After 1 week they returned it. Then I drove again to that city 150 miles away, on the higway at 75 miles per hour and it behaved great. Yet in the city check engine light went off, blinking, car is shaking especially at stops. Check engine light is sometimes blinking sometimes steady but it is there. What is most likely the problem?

hi notcarsmart

there is a common problem with this generation jetta. on the crankcase ventillation system you will find a y-shaped piece of rubber that is prone to disintergration and leaks. check it out and if that is the problem replace it. to reset the light (and you should try to keep this in mind for future use as most of the time that the check engine light(MIL) comes on in these vehicles there is nothing wrong and no codes stored) park the car with the engine running. Open the drivers side door and remove the fuse box panel cover. You will see a series of fuses in there but you need only to focus on the mini ones on top. The fuse you need to pull is the third row down from the top in the centre and is a 10 amp fuse (i believe it is marked as MIL on the fuse directory). Pull it out with the car running. The car will stall out but that is perfectly ok...no harm done. Re-insert the fuse close the panel and restart the engine. The yellow light of doom should now be out. If the light comes on again rather quickly there is probably a fault code stored. Everyone who owns a VW should own their own OBD(On-Board Diagnostics) tool. www.obdtool.com has one specifically for VW's from 1996 to present for around $75.00 and an optional software upgrade for a little more. It only requires that you own a computer to use it (which I believe most people have nowadays). A shop charges you for each time they pull your codes so the first time you use it will pay for itself. Also if you have friends/acquaintances with VW's im sure they'd rather give you $30-40 dollars to pull the codes than give a shop $80. And you can reset the light with the tool. Another more unlikely cause of your light and shake is the MAF(Mass Air Flow) sensor but you would need the diagnostic tool to check or swap it with another Jetta owners known good MAF sensor.

I had the same symptoms and found I had suffered from turbo failure and the final cost at the dealer was $3500, last VW I will ever own. I hope this isn't your trouble too, good luck

Guys, what you are experiencing is the car built warning system. When your engine light blinks it indicates a Major Problem has occurred or is occurring in the engine. When this occurs the cars goes into a "safe," mode which means all power is cut by at least half in an effort to save the car from more major damage. You can take your VW to any large chain autoparts store (autozone, advance, etc) a lot of them are offering a free engine diagnosis. Do this if possible to see where the problems maybe coming from and ways to fix them.

Hi,first thing your cambelt and tensioner should have been replaced 13k miles ago,it would pay you to replace the water pump at the same time as they are known for impellor failure = cooling system fault=P2181 code,hope this helps.
