last time i experienced the same symptoms, it turned out to be the alternator bearings, try taking off your aux belts and then see if the noise has disappeared?... doing this will rule out quite a lot of things.... HTH Phil

everytime i have seen this i have resolved it 100% by replacing all vacuum pipes including the pipe inside the ecu replace all pipes with silicon as they last longer dont squash easily and dont internally collapse under vacuum

i also have one and im in haverhill

I would change all the vacuum lines, this is usually linked with both hunting and with turbo causing limp mode. also EVERY time i have seen 65535 - Internal Controller Error this has been caused by just aged vacuum line INSIDE the ECU, its only a length about 10-15 cm long, replace all your vacuum lines with silicon pipe instead as it lasts longer and is cheap, and does not split and crack with age.

Hi Code is 1022

Guys, Does this Affect only the MK2 or are there other makes this affects? Phil

well im thinking i will try and fit a webasto heater to mine, i cant get hold of a D3wz ECU 2nd hand at a decent price and d5's are generally too expensive, but the Webasto Thermo Top C is a 5kw pre heater an is more readily available. Any one else Retro fitted one of these?, what was you experience? Phil

Hi, my aux heater ecu has decided to fry itself, has anyone an ECU? Or a D5W that they are considering to be lighter of? Thanks Phil

Nice Fix :-)

That is because the K Line of the aux heater is not connected to the cars wiring loom, if you want to run vag-com on the heater then you can by connecting the vag-com k line to the blue and white cable of the heater and connecting -v to vagcom signal and ground and connect +v to vagcom +supply, if you want more info with a drawing of the connections just ask and i will make one for you, but it is possible to connect it bypassing the car's loom.

Hi Nige, I can confirm the MK1 IS a Dumb Unit, it does have a control unit but it doesnt "lock out", it tries 3 times then stops trying until you turn off the ignition and remove the key, then the unit resets it's try counter. Also due to it being a Dumb unit you CANNOT interrogate it via Vag-Com, only via the Eberspacher diagnosis tools. The Mk2 However CAN be interrogated via Vag-Com and WILL "Lock Out" after 3 failed attempts to start, can be diagnosed via vag-Com and reset via Vag-Com. Hope This Helps Phil

ahh Mirez, you beat me to it :-) Phil

My MK1 Alhambra certainly doesn't, im wondering if TIS is displaying that as it is needed if you have the factory "Parking Heater" Upgrade, you know the clock is replaced from the 2 button to the 4 button to allow it to be turned on "on demand" even when the car is not running? Phil P.s. Although i am going to be fitting the pump anyway :-)

Check This link out as a starting point TDI Club Forum, but this issue is generally related to the relay 109 problem, the poor running could just be a knock on effect of the relay not tripping in. Vag-Com would not report the relay issue as the relay powers the ECU so if the Relay is NOT switching ON the ECU then there is nothing to log or to record the event, if that makes sense. Hope This Helps. Phil

oh yer forgot to mention that one mikej, also another one it to make sure the towing hitch cover is fitted as water has a direct path through that and onto the belt. Phil
