Hyundai i30 ESP OFF light and other faults

DarraghR

I recently bought a second hand 2010 1.4 i30 and 2 weeks later I am experiencing a concerning issue. Below are the symptoms that I am having.

Car wont start on first try roughly 1 out of 12 times
ESP OFF light displayed on dash display and only clears when car is started up again.
Rev counter does not move even when I press on the accelerator
Car seems to be revving itself when ESP OFF light is no with non functioning rev counter
Signs that car has slightly lower power or acceleration than expected

I have read a lot of posts regarding similar symptoms but non mentioned the car revving itself. I have compiled a list of faults below gathered from other posts.

Battery fault
Crank shaft sensor
Tyre pressure (My back right tyre looks a little down compared to the rest but my symptoms wouldn't result in this being the fault... would it?
Electrics under steering wheel
Sensor in steering wheel
Steering angle sensor
Faulty break light switch
Break Sensor
Bulbs need to be changed

That is quite a list of possibilities. I have also read that i30's between 2009 - 2010 have had recalls with this issue but my car is well out of the 5 year warranty.

I bought a bluetooth OBD diagnostics Torque Pro ELM 327 for checking fault codes. Can anyone recommend the best app to buy for my android phone.

You need to start by getting the car properly fault checked, too many things going on to guess. No matter what software elm OBD will not cut it when it gets beyond basic engine faults.

That said you have common symptoms of a throttle body issue, as that could effect starting and esp, but that doe not explain the rev counter so more than 1 issue i expect.

You do not need to be within the warranty period to be covered by a recall. Your local main dealer will be able to tell you if it is due a recall. There should be no charge.

Fix was a replacement crankshaft sensor that cost €55 and fitted myself

The first problem are simple to test by fuel pressure meter. If fuel leaks back to the tank or injectors are leaky, then it takes just a time before it restores the fuel pressure. The tester cost about 30eur.

Too many other errors may generated by bad battery or generator.
