Help! Stranded in Asda car park! - Interior/Exterior/Lights/Glass/Alarms/ICE/HVAC/Other - The Lotus Forums #ForTheOwners Jump to content

Cannot start my car, key works, unlocks doors everything. Battery is charged. Dash looks fine except no immobiliser light, doesn't even flash so I can't enter manual code. Aarrrgh! 

Yesterday I was stuck at a petrol station, but was able to enter manual code. That was a sainsburys, so maybe these cars just don't like supermarkets?!

Thanks Bibs, been in touch with customer care at Hethel, Neil suggested calling Lotus Assist, but I've been back to the car, and the bugger started first try! I'm baffled. Can only imagine a fault has cleared or something. The car is likely going in to have some warranty work soon, so i'll ask for fault codes to be checked and post any results/causes.

Above your right knee, where the sill meets the dash.

It points vertically down from the dash. Not got a pic, but I hope thats a good enough description.

Thanks Cocopops, i'm in car park at a golf club, gates shut in 15 so guess this will need recovering tomorrow, by which time I bet it starts again so they won't take the vehicle.

So, after waiting 2hours, the car started again, drove home, tried to start again, nothing. Called for assistance, they came, diagnostics showed P0601 error. Any ideas?

Google it. A quick look myself suggests the ECU self-check isn't working so there's a problem with that. Page 37 of this document...

That means basically that the car doesn't agree with the state it's in on start up is the same as when it last shut down. While I'm no expert I'd guess that either the software has become corrupt and needs to be reloaded or there's a problem with the memory on the ECU.

Yep, what Lord @Bibs said.

Checksum issue according to the Evora ECU guide.

Page 57 for P0601 and P0606

ECU Integrity

P0601 Checksum P0606 Watchdog

Description

These codes are used by the ECU to check the integrity of the software and calibration data.
P0601 checks that on power up the checksum for calibration data is the same as checksum saved on the previous power down.
P0606 checks the watchdog timer after a defined period to see if it has reset. If the watchdog timer has not reset then the code has entered an unplanned loop or condition stopping it resetting the timer.

Monitor

• P0601 at ECU power up
• P0606 continuously while the engine running

Diagnostic Mask:

• The MIL will be illuminated if a fault is present.

Guys, thanks for the help. Waiting on a response from Lotus as the car is in warranty still. Thankfully, it started this morning so I made it to work today -tried to start it again when I got here and again it's failed.

I'm guessing a new ECU.

possibly look at look for some kind of earthing issue?
