coolant temperature sensor

[JKing]

Managed to log a few things (still not engine ) with my vag com earlier.

Came up with coolant temperature sensor intermittant fault.

After reading on here it might explain my poor running recently so hopefully the dealer has stock and I'll pick one up tomorrow.

Does anyone have a pic where the sensor is located + is this the right code for the new one, 059919501a??

Thanks

sorry mate but dont think that will reduce performance
theres another thread about this which i posted in

anyway the temp sender is inside the water bottle. ull see a plug on the side of the bottle? well that plugs into the sensor and a new one means a new bottle. not a big deal tbh prob wont be in stock as this is a 5 years old car, unless its a big parts dept

also is ur water temp gauge playing?? the sign of a faulty sensor is beeping and bad readings on the gauge??

Don't think we're on about the same sensor mate, the pick below is the one I'm talking about. Common problem apparently and can cause the car to run rich. I should get the newer green sensor as opposed to the black one I currently have.

thats the kiddy, you need a green plastic one, the old ones are black and prone to failiure.

its not the one in the bottle.

yeah i didn't think it was the bottle one after reading through some previous posts. Looks to be very common problem so I'm hoping the dealer will have stock. Might pick up a LCR front splitter while I'm down there

Shame I couldn't log contoller 01 Engine to see what else might be wrong, need to order a decent VAG COM cable.

Mine came up with an error so i changed mine. Was £17 i think from my mate who works for VW Service department so trade price.

ahhh my bad sorry mate...i didnt even know about that

Might check this out tomorrow when I have some time..

seems to be very common, the original black coloured sender is prone to failure hence why they revised the part and its now green. Seems to happen across the VAG range not just Seats

I had the same problem, replaced the sensor and I am still having the same problem, same fault. I guess it could be the lambda although my MAF flow rates are horrible too.

I had the same problem as you with the cable too, bought one of these off eBay instead of the USB > rs232 convertor and works perfect:

my cable is serial not usb?

What was the exact fault you had, cooland temp sensor intermittant something or other??

Did you clear the fault with Vag com after you fitted the new sensor??

your cable will be serial and use a USB convertor I guess? Or do you have a serial port on your laptop?

I'll codes i was and still am getting are:

17536 - Fuel Trim: Bank 1 (Mult): System too Lean
P1128 - 35-00 - -
01039 - Coolant Temperature Sensor (G2)
30-10 - Open or Short to B+ - Intermittent


I have cleared the code and reset the ECU. Temp sensor error comes back straight away, fuelling problem can take a bit longer.

No I have a serial connection on my laptop. going to order a cable from here http://www.gendan.co.uk/product_VAG409.html

Mine was coolant temp sensor intermittant, not sure if i have system too lean as I can't log engine at the mo. This was logged under instruments, controller 17 IIRC
