Following on from Twelth's rough running thread, our Shogun was running really roughly and power was way down. Towing a full livestock trailer a few weeks ago was almost comically difficult. EGR / decoking issue was diagnosed. So today, it is off to the Mitsubishi dealer in Telford for an EGR valve check / fix / replacement, plus manifold / head off decoke (acid bath job) and clean up. I'm expecting a bill around £1000. They need it all week.
But that's not bad for an 8 year old 66,000 truck. It is the first larger non routine bill we've had. In fact it has been utterly reliable as a vehicle.
I'm getting a loan car - not sure yet what that will be.

I feel your pain, but likewise I've only really had to deal with 'consumables' in ten and a half years/74k miles. 'It could be worse' is the only sensible mantra!

It seems a bit expensive for something that's only done 66k miles, I'm not sure I'd be very happy with Mitsubishi for presenting me with a bill like that, but perhaps the issues are a function of that low mileage?

8,000 miles p.a. might be a little low, but it's not like it's granny's used-once-a-month Micra!

What are the options of fuel additives to reduce coking etc? Any of the worth using?

It's not an issue I've ever had in my older cars, just seems to affect modern machinery. I wonder if the regular activity of blocking off the EGR valve is a help?

I'm pretty sure that EGR valves are the big culprit in engines coking up.

The Shogun has a 3.2 litre 4 pot diesel engine. It's more like a ships engine than the higher revving modern turbo stuff. Apparently, them coking up is a known issue - usually EGR related. |

I'm not sure that's the panacea I'd hoped for - I use V-Power all the time and whilst I can believe it delayed matters, it didn't prevent them. |

But that may be tempting fate..... |

I worked in a Mitsubishi franchise for a while and remember there was a SWB 09 plate Shogun berthed there for a while - engine stripped, waiting on a decision from Mitsubishi/the owner about going ahead.
I'm sure the techs whinged about it not being unusual.
Mind you they said that about a lot of things - earlier 2.5 litre L200s were notorious for head gaskets but, according to them, the '90s Shoguns were fine because their engines were made in a factory in Japan rather than Vietnam or somewhere like that. |

I just picked the Shogun up from the dealer. It was ready two days early. The EGR was fine, the whole thing was just crudded up. The manifold has had an acid bath, no parts were required and the total bill was "only" £480 compared to the "up to £1000" I was quoted. And when I drove it, it seemed like a new car. I suspect the power had been decreasing for some time and we'd not noticed as it was incremental, until it became terrible. Accelerating away in top and real urge was back. OK, I've not tried it with 3 tones on the back yet, but I suspect we'll really notice the difference.
I asked the dealer what was the best way to avoid the issue reoccurring? A monthly Italian tune up was the recommended solution. I might also buy ultra-diesel, or its equivalent, every few tank fulls to see if that helps.
But one word on customer service. They had our car for three days. It came back unwashed.

This car washing thing by garages is a modern fad, it'll never last.
I'm in my 50's and until about 4 years ago, my cars (and going back many years, my parents' cars) were never washed when they went to the garage for servicing or other work

I'd be blanking the EGR off now the intake is lovely and clean.

Audi always do it, and so did the indy that did my car - but then they'd had it for three weeks (because of my holiday), and it had got rather grubby stuck in their workshops so I think they felt obliged.

I'm pretty sure that EGR valves are the big culprit in engines coking up. Nail. Head. I've lost the pictures on the old forum, but the sheer amount of shite that was clogging up my inlet manifold when I removed it last year was unbelievable. I've since severely restricted the EGR with a restrictor plate because cleaning the inlet manifold on my car requires removal of the cambelt and HPF pump. |

An oil change and quick kick of the tyres. It's just common courtesy by garages to do it. |

The independent I used to work at washed all cars that were in for any work, no matter how scabby the car was (at least once a potential customer had parked in the wash bay and the apprentice did their car!!)
I was disappointed when my 2002 vintage 320 went to the main dealer for its airbag recall and came back just as filthy as when it went in, it made me want to NOT give them the business when the current 320 went for a service, sadly the preferred dealer in Perth weren't offering a courtesy car so my plan was scuppered.

No car washing when my company car went to 'Nobbys Tyres' for servicing, but all main dealers I've used have included a car wash, unless I've asked them not to. Porsche do a decent job of cleaning the car outside and in, no matter what it's in for and did promise to clean it any time we were passing, but that's not been tested.

To be fair, maybe they just thought you'd look a bit odd driving a clean Shogun. They might have been trying to avoid you being the butt of fellow farmers jokes if you were driving around looking like a townie in a nice clean SUV!

The Captur was in for it's annual service today (only done just over 5k since last year) and it was washed outside and cleaned inside. Not a full valet but a welcome spruce up. We were told on booking that it was optional and would cost 7 quid so we agreed as it saved us a job. The service was included in the 4 year package the previous owner bought so that was nil cost and the wash was, on collection, given to us for free as well. Happy days. PG, glad to hear the Shogun is back on form and at less than expected cost. |
