HELP! TDI power cut!

teedeeye · 08-07-2005, 18:52

Problems continue with my very high mileage TDI Elegance.

Whilst returning my car to my local dealer to rectify another fault the other day, I suffered a sudden electrical power failure. This manifested itself by:

radio switched itself off
ABS, ASR, seatbelt, airbag, PAS lights.... lit!
indicators go mad
Complete failure of PAS (quite alarming when negotiating roundabouts)!
once stopped, car fails to start (flat battery)

Just got the car back from the dealers after they'd had it for 9 days; they'd stuffed up a number of jobs and had a lot of sorting out to do!!! Amongst many other things, they replaced the voltage regulator due to an 'intermitant charging problem'.

Anyway on my return home tonight I was feeling quite pleased as it seemed they'd finally sorted all my other problems (FOC) and the car was running better than ever. 10 miles into my journey and.... Blackpool illuminations and no PAS - AGAIN! After limping home and switching off, the car once again fails to start a la flat battery.

I've rang the dealer who suggests I try a new battery. My question is, what is the correct capacity (AHr) battery for the TDI PD 100 BHP Elegance? Anybody have any alternative ideas/suggestions?

Battery is 70 Amp/Hrs, same as a vRS.

Tom_vRS · 08-07-2005, 19:02

How many miles is very high?

teedeeye · 08-07-2005, 19:17

Just checked, current battery is just 44AHr! That aint gonna help matters!

No it wont, and to be honest im a little suprised in the whole time it was at the dealers that rather glaringly obvious fault wasnt noticed. Your alternator will be working flat out trying to keep that little thing charged and will be failing miserably.

Get yourself a propper battery and you should find all wil be ok.

That is a puny battery for a diesel let alone one with the presumably heavy demands of the electro-hydraulic pump for the PAS.

WW_VRS · 08-07-2005, 19:37

Ouch that's the same as my rover 100 :| (dunno if that's standard, but in any case).

Replaced mine with a heavy duty one from Halfords - £60 with a 3 year warranty

Will anything terrible happen when I momentarily disconect the battery? ie, radio code, service indicator.....?

Lummox · 08-07-2005, 20:26

You will loose the radio code, but if you flick the ignition on it should go ino learn mode and recode.

Just the clock to reset

My wifes Fabia had been stood a while so the dealer had stuck a battery on it from a 1.2HTP.

We were getting power steering warning lights and intermittant problems.

New heavy duty correct size battery sorted it out.

Cheers

The engine ECU will also lose its 'learned' settings and will revert base factory settings.
