Engine Management Light on intermittently - fault code 17664

[Samba123]

Hi there,

First post, but been lurking for a while now. Great forums!

Need some advice - I have a 2003 Seat Leon SX TDI. I've had a problem with engine management light appearing intermiitently, but car itself seems to be running fine. I have a VAG fault code reader and read the code off as 17664 which unfortunately wasn't listed in my supplied manual.

However the guide here shows it as:
17664 P1256 Engine Coolant Temp.Circ Open/Short to B+

Now I'm no mechanic so what does this mean, should I get it to a garage asap or am I ok to keep on driving it until I can get it in?

Cheers for any advice...

Hi mate did you ever find out the problem with this as i have a Audi A4 TDi with same error code. Engine managment lights comes on ever now and again and diag machine says it has a sporadic problem with the code P1256 17664.
I was just going to change the coolant sensor, sounds like your problem is the same as mine.

Thanks.

I wish people would use the search function, thats what its there for

Seriously guys, this is probably the most common fault with the car and there are thousands of posts regarding this subject. We dont need yet another thread

Yes plenty of posts with no real answers, all very well if people identified the problems and the cures instead of speculating. A list of error codes with no fixes doesn't really help that is why i asked the question.

Hiya,

Yes - did get it sorted. It was the coolant sensor which as Mitchy says and my local VW specialist told me is a very common fault.

Cost me about £55 incl labour to get it fixed.

Cheers...
