1.9 dti somkes like hell when running - Passat Volkswagen Cars & Trucks

Hi. I own a Corsa Bakkie utility 1.7 DTi. My problem is that the petrol light keeps flucking and the gauge does not work. I took it in for repairs and was told that my pump and gauge are working well but there is an electrical problem. Can you please assist

You have the Y17 DT (Isuzu) engine.

It could be an Immobilizer fault, if the spanner /car light comes on.
If you have a spare key, try it
A Flashing spanner light normally means immobiliser fault hence the non-start. The spanner light left might just be an indication that it has stored the "wrong transponder" code.
Opel will have to clear this but you might need a CIM as well that is the bit that reads the key to allow it to start.
Try the spare key if you have one

On 1.7 DTi models, a defective solenoid in the pump can cause failure of the ECU due to excessive current draw causing components to burn out. but this *should* cause other fault codes to appear.

It's running too rich, most likely the choke mechanisms aren't coming off when the engine is warm.

if its just at start up its no bid deal- jjust a little oil running down the valves at shut down-new valve stem seals would stop it but thats not going to hurt anything -if its all the time after it warms up- then you've got a problem-at least have to do a piston ring job-denny

If you're seeing blue smoke it's from oil burning and indicates bad valve guide seals. At idle the engine vacuum is high and sucks oil through the valve guides. If it's white smoke it's from burning coolant in the cylinders indicating a cracked head or leaking head gasket.

Oil rings on the pistons are bad. This is a engine rebuild or replace you can still drive it, just keep check on the oil level

sounds more like a carbon issue on the piston rings. i would run an oil cleaner such as BG #109, i have seen excellent results with this. worth a try for the price ( about $20 for a can).

Black smoke usually means a rich mixture. For some reason the car is getting too much fuel. If the check engine light is on then take it to a shop with a code reader. They can tell you what sensor needs replacing. These newer cars are usually totally computer controled so if a sensor goes bad they will adjust the mixture incorrectly.
