Title: ESP Warning light and Radio not working
Post by: Philip Meldrum on April 14, 2018, 01:30:49 PM
I have a 2009 Seat Alhambra
Some time ago the ESP warning light came on, and around the same time the radio stopped working.
I thought is was probably just a fuse, but checked the one for the radio and it was fine.

Took the car to our mechanic and his diagnostic kit identified the clock-spring as the problem.
This was duly replaced, but the warning light remained on.
They also checked the Radio, and it appeared to have power, but just would not work.

Speaking with his spares dealer, they suggested it could be the 'central control unit' £1,500!
So we took it to the local Seat dealer for diagnosis.

The Seat dealer also came back with the clock-spring, and when we explained it had been replaced, checked it again, "checked all the relays and earthing points. Seat believe it is a wiring fault, and estimate £500 plus to go through the whole wiring loom

I'm not convinced - would this also explain why the radio is not working?
And our mechanic still suspects the central control unit...

So has anyone seen this kind of fault before?
Any ideas?
I read somewhere about there being TWO fuses for the radio - does anyone know if this applies to the Alhambra Mk1?

Can't see how to edit the post, so a quick correction - its a 2009 NOT 1999

I should add that I replaced the radio with a second hand one, and we also tried a radio that we knew worked, and it did not work.
But the Radio appears to have power...

I'd suggest you get hold of VCDS as a starting point. the lite version and a cable can be found on eBay for less than a Tenner. Can't see how the esp would have anything to do with the clock spring, usually that only causes the airbag light to come on.

The exact errors still being logged should give you a clue whats going on

What doesn't work on the radio? Is it failing to respond at all, or just doing everything except making sound?

You have a MK2 Alhambra if its a 2009 vehicle.

Thanks Brianh
The radio is completely dead...

I will try to get the error codes from my mechanic, or Seat.

I think it is a Mark1 - no sliding doors, and removable rear seats rather than folding. I think it was a late registration or something...
(We bought it second hand 3 years ago)

No, Brian is right, it's a mark 2 -  built from 2000-2010.

Mark 1 is from 1994-2000.

The exact fault codes would be probably be useful. I remember someone else had a very similar problem a long time ago - radio and ESP not working, but I think the VAG-COM fault showing was 'steering angle sensor', not airbag/clockspring related.

I'm sure it was something to do with a 12V supply to various circuits being missing, maybe fuse 32? Not certain about that, but there was a fault in the wiring loom somewhere.

Isn’t there a bunch of wires spliced under carpet/sill trim on passenger side that causes electrical gremlins?

Have a look in ref library as some info there.

There definitely is on the mk1 - front passenger side around where your feet would be if sat on the seat. Can be accessed by removing the side trim around the door and lifting the carpet up. I would expect the same path is used in the mk2 as they are quite similar. Think the usual cause of problems there is corrosion to the harness due to the rear washer leaking where the pipe joins and is held together by luck mostly just above the footwell.

Splice joint 32 and fuse 32 are certainly candidates for your problems, unfortunately the symptoms are not always the same as it depends where the high resistance is on the splice joint.
From memory there are five or six red and white wires bundled together depending on the spec of the car.

Thanks for the tips.
I guess I need to take a deep breath and check the wiring...

Before you do that, try and get hold of a VCDS cable (eBay cheapest bet, should be able to find one for less than £10 easily). Then find a laptop from someone if you haven't got one, install the drivers for the cable (that come with it) and VCDS lite from Ross-tech (free) and connect it to the car, do a fault code scan and see what comes up.

It turns out the ESP usually has a steering wheel angle sensor, which may be the reason for the clock spring diagnosis you've been given already. (I can't confirm this to be the case for the Alhambra though) But it may also be the case that you actually need to clear the error before the light will go out. Don't know for sure, but your stabbing in the dark a bit without knowing what its complaining about to start with, and before you delve further into the wiring it would be a good idea to make sure you aren't introducing further problems (at least then if fresh codes come up you might know what you've done to upset it further and be able to fix it!)

I think the steering angle sensor fault is often one of the clues. The fault causes the ESP to stop working, and the sensor is supplied by the 12v supply involved in the bunch of wires mentioned above.

Hi, did you ever get to the bottom of this? My Alhambra is doing exactly the same thing.. ☹️
Title: Re: ESP Warning light and Radio not working
Post by: Steve-SETDI on April 09, 2021, 08:18:27 PM
Code is 00778 -.No Comms with steering angle sensor.

The wires referred to as splice 32 are relatively easy to get to - you just need to remove the trim piece on the passenger side that goes round the door opening to get to it. bundle of a few wires twisted together. They get drowned if the usual fault of the rear washer not working happens (where the pipe seperates in the footwell area).

How can the radio not work if it has power???

I’d just out a new head unit in, you can get some really nice DAB ones these days quite cheaply.

Not sure about the extra sensory perception thing but does it really matter anyway, I think most Alhambs don’t have it anyway
Title: Re: ESP Warning light and Radio not working
Post by: brianh on April 10, 2021, 09:17:13 AM
Yes it does matter, as if its fitted and not working, it will fail an mot

https://www.gov.uk/guidance/mot-inspection-manual-for-private-passenger-and-light-commercial-vehicles/7-other-equipment

Section 7.12

"You must check all vehicles fitted with electronic stability control other than Class 3 vehicles.

Electronic stability control is also referred to as ESC, ESP, VDC, and DSC, among many other names. Some systems may be able to be switched off by a switch, whilst others might only be able to be switched off using an electronic menu system.

The dashboard warning lamp for these systems might take various forms and you should only fail a vehicle if you’re certain that the warning lamp is indicating an ESC malfunction. You might need to check the owner’s handbook."

It is a safety feature after all, so you probabbly actually want it to work!

I don't know if the later vehicles upgraded the sound system, possibly including an amp or similar and maybe that isn't getting any power, so the radio "works" in as much as it comes on, you can press buttons, but can't get any sound out of it? Or even if Steve doesn't have exactly the same issue, but just has the esp light and same error code coming up, but no problem with the radio. Given the amount of wires involved in the splice mentioned, its possible to get different faults if the joint isn't in good condition and some of the wires aren't properly connected.

I am going to check splice 32 today hopefully so I will update.

Mine also has a rare multifunction steering wheel and the controls or the horn won't work either.
Title: Re: ESP Warning light and Radio not working
Post by: brianh on April 10, 2021, 09:52:09 AM
The horn does seem to be mentioned when this combination shows up, I'd expect its possible the multifunction buttons are supplied from the same source as well. Good luck!

Are the wires in spline 32 all suppose to be connected together?

Mine are like this..

Title: Re: ESP Warning light and Radio not working
Post by: Steve-SETDI on April 10, 2021, 12:41:32 PM
Sorted. All wires soldered and everything now working again.

Thanks very much for the replies to this thread. Very much appreciated.

well done Steve I think that's the worst affected S32 I've seen [GJ]

I had been looking a fix for 18months so it's had plenty of time to melt away lol!

Just for clarity for anyone else having this problem, Yes they should be all connected together like you've now done!

Thanks for posting back with the result, helps other folk out in the future!
