TVR Cerbera speed 6 HELP PLEASE
Discussion
First job is to replace the battery with a new one.
TVR's love to play silly buggers when the battery is on the way out, even if the voltage appears to be ok. Replace it with a high spec gel cell battery such as an Optima Red Top. A bit pricey but they've got so much more power, especially for cranking. They also hold their charge better and can handle being discharged without damage, unlike a typical lead acid.

Hi, if i remember rightly , when I had my cerb. Disconnect the battery, reconnect, and press and hold the fob, which should then reset the alarm/imobiliser etc.
I had the info somewhere. Hopefully just you imobiliser.
My cerb needed to live on a trickle charger as would go flat in about 10 days at this time of year, but would be fine in the summer months.

Hi David - I run a Speed 6 Cerb in Australia and have been through most of the problems commonly reported on here!
I totally agree about upgraded the big fuse and getting a high quality high output battery. One of the car's little flaws has been an inability to crank the engine when hot with the standard fitted starter motor and an ageing battery. As for the MiL light, it is worth earthing the whole engine and chassis and then connecting the new battery,, plus trying the fob reset, after turning the key you're told not to touch off an on, but... sometimes the fault codes need resetting . This can be done by connecting the ECU to an old computer running Windows XP with the MBE derived diagnostic software. I have a copy of this and any TVR recognised dealer/servicer worth their salt should have it, but you may need to install a new three lead connector to interface the laptop with the ECU if you do it yourself. You will need a TVR wiring diagram to sort this. Dulford Automotive supplied everything I needed including a copy of the software and wiring diagram. [Where do you live?} I do my own diagnostics now and the MiL light stays off - hooray.
You may have problems that have not been mentioned on here e.g. failed lambda sensor, incorrect air fuel ratios or a disconnected sensor. The oil pressure is measured by two sensors one essentially mechanical, the other electrical. They compare outputs and if these disagree or the earth lead is not connected on the electrical sensor the MiL will come on.
If you are close to somewhere decent like TVR Power, Racing Green or Dulford I would suggest getting them to look. Most MiL light faults don't preclude running the engine, but some others.... you get my drift.
Good luck, Cerb owning can be a bit frustrating (& expensive) , but it's tons of fun!
