Dashboard is a Christmas tree!

[Whitelionel]

Hi all! New here so I appreciate any input at all!

Had my 17 Plate FR Tech for 5 years now, besides having the silicone bag split it's been fine up until recently!

Car generally turns over and runs fine, however a few weeks ago I had a tyre pressure sensor tell me I had a flat, upon checking they all seemed fine and carried on.

Week later whenever the car is up to temp, the card momentarily slows down for a very brief second and then carries on fine for the rest of my journey, it's done it a few times now until yesterday when most of my dash lit up with errors such as "ESC disabled, Tyre pressure low, Automatic brake disabled amongst a few others (no Eng Management light thankfully!).

Pulled over, restarted the engine and everything disappeared and drove 20mi home. It also slowed slightly as stated previously before lighting up.

I'm absolutely baffled what could be causing this, my OBD reader states no fault codes found so I'm at a loss as generally it's fine.

I've heard this could be a battery fault but surely the car wouldn't turn over as a result?

I'll be taking this to the garage soon as I have no experience with modern cars but any indications I can supply would be great!

Many thanks

Failing battery can cause such electrical malarky, but then so can dud ABS sensors and dodgy brake light switches.
It's a game of parts darts without getting into reading the codes. I'd be checking the resting voltage on the battery first.

An ABS sensor failing is a good shout. With the appropriate equipment, you won't be able to read the ABS module faults though.

Your tyre pressure is "measured" by the ABS sensor when up to speed, so that's a good clue and would tie in with the error lights you've got.

Which OBD reader are you using?

Oh I don't really trust my reader, it was a cheap ebay jobbie for an older car. I've never needed to use it for 5 years so it probably needs to get to the garage to be checked with a decent reader.

I'll get my multimeter from work tomorrow and test the battery. But it's going in for its Mot next week so I'll ask for them to take a look and see if there are any Abs sensor errors.

Many thanks for the input so far!
