Just scanned a 2011 VW Sharan 2.0 TDI with a MIL light on. Fault with reductant heater. Thought I'd post to see if a common fault and see if I could post a full scan correct?

Any ideas? (I haven't looked myself yet)

I've just spoken to TPS (Volkswagen Trade Parts) and common replacement of reductant heater £516.12 +vat and / or module £290.31 +vat.

I will do some wiring checks later on today when I get time.

MIL light does clear and fault is intermittent.

My question is, can I code the module if required or does anyone know if it is plugs 'n' play?

Fault is an intermittent open circuit / under voltage to auxiliary heater element, which TPS think is more likely module fault. Depends really on if the under voltage code is created by an actual voltage test or the fact the temperature sensor in tank doesn't warm up as expected?

Change the heater and or check wiring to it if tests good..........and ultimately ECU in rare some cases as per the RTFB.

Should just plug in if just the element purchased......

There is a heater repair kit for abt. 200 Euros, part # 7N0198970A, it is pretty easy to install, just take off the rear bumper and the inner fender liner, and unbolt and lower the tank, screw out the older heater and screw in the new one, plug it in and put everything back in place - done!

Wow, thanks guy. Shows forums are worth the time.

Heater repair kit good number, but currently on back order 5 - 10 days. Cleared codes and driven 10 miles, so going to let customer have it back and order repair kit. Got to be worth a go at £180.91+VAT. Slightly annoyed TPS weren't forth coming with repair kit when I phoned this morning.

BTW, I just saw there is also a "B"-Version of this repair kit - 7N0198970B - but could not find much further information so you may want to ask your parts guy if this is the replacement part for the "A"-Version and if he got you the right part this time
