2006 IS220d - Is it possible to bypass the immobiliser!

[Gaain P-W]

Hi

I've had my weird green 220d SE-L for about 7 years. Love it and no problems at all until..........

happily drove from Chester to Cheltenham and back in a day, no issues as usual. Next morning, started for 2 seconds and died.

Long story short, garage cant find the fault with immobiliser, swappd ECU's (??) and said due to age and value, sell it on for spares!...... they left me with a big box of parts they swapped out to boot too!

Bit loathed as it's usually a dream to drive and I'd just spent £350 getting the alloys ground and refurbished! 😞

Is there a simple way of bypassing the immobiliser to see if it will start. Not bothered about the security aspect as it's 16 years old and worth about £2k on a good day!

Any suggestions welcome!

Thanks

I don't know the answer but doubt there would be a simple way, rather defeating the object.

I would strongly suggest if someone does know they don't post it on the open forum!

Private messaging you would be the 'secure' method...

Answer - there is NO WAY to bypass immobiliser (so don't worry about private messaging), I recently (around March) did full ECU kit replacement because my immobiliser was acting-up.

It would be good to know the codes you getting and what box of part they have returned to you, what they have changed, what they have tried. I may have semi functional "ECU kit" one I am finished with my car and it may help diagnostics.

Thanks Linas.P

I'll see what's in the box of bits and have a word with the guys in the garage.

Great colour...same as my IS250. B0rked ECU is a bad problem and costly to fix I'm afraid. I write as one who has the receipts.

There are a lot of IS220d being broken for parts, so getting ECU kit is not necessary that big of an issue, new one obviously would be very expensive. However, the bigger issue is diagnosing the issue correctly and the access is very difficult as well - in my case it wasn't even immobiliser which was main issue, but electrical issue somewhere.
