Kia Sedona Various Problems

[grifter]

Hi

I am trying to help my neighbour with his Kia Sedona 56 plate, it is really slow on pick up and has various issues, including engine light/ABS light and glow plug light flashing, he uses it as a works van basically, going to jobs to do kitchen installs and has used it for years with just basic maintenance as and when needed.

He has traditionally used a local well-recommended garage for MOT, plus a relative he's since fell out with to do repairs etc. and so I mentioned to go and get all the codes read out, apparently the garage said they had a problem actually getting the diagnostic plug to connect up (No idea why, never heard this happening), so he bought a cheap reader now, which I'm certain won't give all the codes out (if it even worked), although I've not tried it.

Does anyone on here know anything about these cars, if they are turbo charged? Also what might be causing engine light on and glow plug lights to flash, it's seems to start ok from cold. I'm thinking engine might be in limp home given the erratic performance. That and/or a problem with turbo perhaps, if it is turbo charged.

Thanks

Yes it is 2.2 or 2.9 with variable geometry turbo, if it's quite high mileage or been used for mostly short trips then it's my guess it's dirty carbonised vanes in the turbo which can throw up the eml light and put it into limp mode. Many try to clean them their selves but it doesn't really work and if it does it doesn't last long, get it properly diagnosed👍 Could be air flow meter but these don't normally show an eml.

Could also be petrol...

Hateful things. Set light to it.

No, he mentioned glow plugs

I'd say a mix of urban/mway driving and mileage is not huge but I think it's maybe in the 100,000s range. I've said to him to get it diagnosed before doing anything else. Thanks

Managed to get a code out of this it was p0088 common rail high pressure. According to the kia forum this points to a replacement inlet metering valve:

https://www.kiaownersclub.co.uk/threads/p0088-inlet-metering-valve-replacement-guide.47513/#post-307773

Looks like a moderate job to do. Also read people have replaced this and the EML still illuminated, think this was with other codes though p0087/p0088 low and high pressure, guy ended up doing a back leak and the injectors were goosed.

Strange that code seems to clear itself but the light was still illuminated at one point, and you have to drive it and give it a bit of welly before the light pops on (After it's been turned off and sat for a while).

You get all sorts of odd codes if the MAF is dirty/goosed or unmetered air leak ,so worth checking live data ,not saying it's the case here ,just a pointer

Going to try another run with the torque app see what live data is showing.

Wide of the mark......the two systems are mutually exclusive

That's critical, it needs the rail pressure monitoring over load (not sat on the drive revving).

I assume this doesn't have a cheap naff tuning box fitted?

Not that I'm aware of, would a sedona ever have that sort of thing fitted? For what reason?

Very much available, and the usual approach people take to get a bit more go (fools the ECU into thinking the rail pressure is low so it injects more fuel......by modifying the rail pressure signal)
