I have had so...

I have had so many things repaired on my 2008Range Rover yet the check engine light keeps coming back on. The last two thigs were head gaskets and fuel pump.

Mechanic's Assistant: Does the light stay on, or does it blink?

It stays on. The dealer put it on the machine and can't find anything. Needless to say, I am very wary driving it.

Mechanic's Assistant: What is the make/model/year of your car?

Range Rover 2008

Mechanic's Assistant: Are you fixing your Range Rover yourself? What have you tried so far?

No.. I am not. I'm taking it to the mechanic. It began killing on me some months ago. The head gaskets were replaced, the light came back on. After nearly 2 months with the mechanic, it was put on the machine for diagnsis and nothing was found. About 3 weeks ago it killed again. This time the fuel pump ws replaced. I drove it home today and the light was off. I drove tto the neighborhood store and still fine. On the way hme I noticed it was on again

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

According the the dealer, they did every test.

I don't know

Not a problem.

Ask Your Own Car Question

What they should be looking for is an intake or exhaust leak and also a restriction in the fuel system. If the issue is in the fuel system, then the injectors and the pump should be inspected. Here, I am attaching code and vehicle specific information(you are looking at P017100. This information gives you the most probable causes for this light.

Thank you Todd

You should ask them to perform a smoke test on the vehicle. If this test turns out to be good, then the focus should be on the fuel system. This could be a weak pump, a restriction in the lines, or dirty injectors.

They just replaced the fuel pump, so in addition they should perform a smoke test and check for intake and exhaust leaks, yes?

Exactly. This will reveal the most difficult leaks to detect.
