Huge Aston Martin db9 problem after dlatego battery.

[Adach]

Hi Piston Heads!

I have huge problem after flat battery with my 2006 DB9. Car was on garage for about 2 months without battery connected so it gone totally flat.
I took local mechanic to charge battery and start engine (we have just one AM official service about 260 miles from my city). He was charging battery for about 30 minutes then jump start. Everything on first sight went ok, engine started without any problem.

But it is not ok at all, strange things happening, there goes a list:
- windscreen washes starts after ignition on, but after that they dont work, same with wipes,
- ABS/DSC/emergency break dont work with warnings on dashboard,
- aircondition dont work (Button dont react), same with sport button,
- side windows works by steps (it takes five steps to close and open each side window)
- turn lights dont work inside front lamps (side and back lights works well)
- break pedal pulsates after ignition and engine start (even without ignition on there is a light feelable pulsation)

Engine runs all ok, i took two long runs (60 miles) to charge up battery- without any changes.

I was thinking about burned ECU caused by jump start, is it possibile?

Any suggestions to help me solve the issue?

Thanks in advance and sorry for any language mistakes.

Once a battery has run flat it will never perform the same again. I suggest you get a new battery which should clear your multiple issues as they are all a sign of an underperforming battery.

+1 new battery required

Yer try a new battery with the cells have been fully drained there will be issues.

I use a Bosch S5, good price and a 5 year warranty.

Also if the DB9 get no power due to a dead battery or replacing the battery there is a few things you need to do .

Small update - just changed battery for one of recommended. Nothing has changed, still same problems. Plus another two - central radio panel and turn signal dont work at all (not just aircondition and ventilation as before). Took 20 miles trip after changing battery.

Any further ideas? Thanks in advance!

Might be a silly question, but is it a coupe or convertible? If convertible, could be the CRM.

It is coupe db9. In that case CRM is surely not a problem.
