VW 1.6TDi Limp mode woes

mboyFree Member
Jinxed myself incredibly here didn’t I, just as I suspected!
http://singletrackworld.com/forum/topic/vw-caddy-anyone#post-8465846
Van went into limp mode last night (annoyingly just had a full service last week too), have had the code read and cleared, Injector 1 has an intermittent fault. Fantastic! A 6yo vehicle with a mere 63k miles and it’s goosed! Wonderful, seems they don’t build anything to last these days eh…
So I know this is a fairly common fault on these, and main stealers want ridiculous prices. Can anybody please give me some good news about pricing, and/or where to get it done? I’m based in Worcester if anyone knows anyone that can help. I have a guy that could probably do the work, but having heard the prices some places want for the injectors alone, it’s potentially gonna set me back a LOT of money!
There are some 2nd hand injectors on ebay I’ve noticed, obviously caveat emptor and all, but found a full set for £130 from a 17,000 mile old vehicle. Given that they all seem to fail at roughly same age/mileage, would a set from a 2 year old low mileage vehicle be a wise investment, especially as I expect within the next 2 years I’ll have sold the Caddy and replaced it with something newer…? Seems to me that £130 for 4, and pay my mate a few hours labour @ £30 an hour is far more preferable to the £500+ per injector I’ve heard some people have been quoted!
Any input from those who have suffered gratefully appreciated.
trail_ratFree MemberTimely . Not a 1.6tdi but I had to replace an injector on a common rail hp system this week.
I assume you have checked the basics like the plug is good and making good contact the loom is not damaged at any point along its travels .
I dismantled my failed injector and what I found was a substantial amount of debris in and around the ball valve. Under the microscope it could be seen that my ball looked like a cross between a rugby ball and a. Golf ball.
I checked and cleaned all the others while I had it apart and it was only that one exibiting the debris. I have no idea why.
Anyway speak to a diesel injector specialist. They will do refurb oe injectors . Mines are 400+ from the dealer and my refurb was 160 quid. These guys can also test your injector and tell you what if anything is wrong with it blindly believing diagnostics is a bad idea. Mines showed up quid obviously in a leak back test.
Diesel Jones/pf Jones is one and if you can get through my new mates at airylea motors were really helpful yesterday. Or Patterson diesel in fife I think diesel bob has a monster waiting list but he is another – Atlantic diesels also good.
Just watch out as being vag you may need a vagcom to code the correction code to your ECU for that injector.

Assume nothing… I don’t have time to mess around with vehicles myself, just drive em these days. All I know is that it went into limp mode, I’ve had the fault codes read, and it’s an intermittent injector fault. Codes cleared for now, drives ok but hiccups a bit, so I’m expecting said injector to fail any time now.
Anyway speak to a diesel injector specialist.
Monday morning’s activity sorted out… Was trying to do a bit of research in advance to be fair.

Had heard this, and also conflicting stories. Guess I’m gonna find out one way or the other very soon!
trail_ratFree MemberYeah I was told I would need to by internet specialists(IE the forums) but I spoke to someone at iveco and said on my vehicle just plug it in and play the ECU will work it out assuming it’s within parameters and not just thrown together.
But yeah find a good diesel injection specialist near you with a test bed and that will steer you better than going to the dealer. Should be cheaper if not more informative / less parts darts
NobeerinthefridgeFree MemberSpent a bit of time looking at these faults on caddy2k forum, seems the used/refurbished ones are to be avoided.
I don’t think it’s a huge jib changing them out, best bet is to buy the new ones, code ends in s instead of L IIRC And do it yourself.
trail_ratFree MemberWhy no refurb ?
Fwiw there are refurb and there are REFURB
Some eBay cocks just change/clean nozzles and call it a refurb
A propper refurb from an authorised specialist should be indistinguishable from new and come with a 12 month warrenty .
Used should be avoided obviously even I decided that wasn’t worth my time never mind paying someone else to take a chance with an unknown injector.

I’m thinking my best bet would be to buy 1 or 2 second hand out of a low mileage motor, pop them in in place of the dodgy ones, then get the dodgy ones properly refurbed and then leave them on the shelf until another one goes, then just rotate as required…
trail_ratFree MemberTruth be told you have no idea not guarantee of milage your used injectors have done irrespective of the eBay advents arbritary number.
Given injectors do have a service life of about 90-100k after which they are on borrowed time anyway I’d be apprehensive. Some go on for ever I’ll admit but it seems that more need than don’t need in their life.
I’m quite prepared to replace the other 3 injectors in the near future but for now they running well 🙂
As for refurb you will find a propper injector specialist will have them on the shelf ready to go.
somafunkFull MemberThe injector failures on pre 2013 1.6tdi engines were due to faulty insulation on the injector and it cannot be refurbished as it is integral to the unit, loads of issues regarding failure of these injectors on the caddy forum as mentioned above by NoBeerinthefridge and the only genuine cure is to fit new injectors.
You may get away with fitting 2nd hand injectors but if they have the poor insulation design issue then they will go pop at some point.
trail_ratFree MemberMulti meter on ohms look for infinite resistance on the wiring. Although as it’s intermittent I’ll bet it’s only when it’s hot.
If it’s a known fault I’ll be surprised if a propper sanctioned refurb place is letting them through with it.
The windings at the top should be a replaceable part unless these are some super fancy injector and it’s all made as one….but not without a full recalibration and reshim.
fallsoffalotFree MemberWhy not have your own injector refurbed, no need to recode it
somafunkFull MemberThe injectors cannot be refurbed due to the insulation issues
trail_ratFree MemberWhy not ?
You change the nozzle you change the calibration .
Coding the injector to the ECU isn’t to tell it it has a new injector it’s to apply the correct correction factor to the fuel trim. Thy are calibrated to a “tolerance” and the test machine spits out a code to be put into the ECU to recalibrate the fuel trim.
NobeerinthefridgeFree MemberAye, it’s an electrical (insulation) fault as Soma says, that can’t be rectified, despite what what some sellers claim.
And VW ain’t acknowledging it.
Imagine that.
fallsoffalotFree MemberHave no idea how my sons car started and worked ok.focus 1.8 tdci would not start told it was injector leak back.took out the injectors and had them refurbed and then put them back in the same piston they were removed from worked fine. I am probs missing something somewhere though.
trail_ratFree Memberto an extent you get away with it with some cars, very little to do with the fact he had his own refurbed more that they were refurbed to good tollerance.
as for owning VW my mk4 golf was enough. pig to work on , expensive , hateful place to sit. Give me a mk1 driver or a breadvan polo any day vw peaked in the 80s/early 90s for me.
NobeerinthefridgeFree MemberWhen I was an apprentice, always wanted a golf driver. Ended up with a nova sr. Now that was a shit car!.
StonerFree Membermboy – Im sure Ive heard theres an injector refurb chap in Worcester. I can ask about in the pub tomorrow night but otherwise keep looking as Ive heard theyre alright.
mboyFree MemberStoner much appreciated.
There’s a good diesel specialist over in Malvern too I’ve heard. Problem is I darent go very far in it in case it goes back into limp!
jondFree MemberRecovery bloke that picked me up reckoned that the fault often clears and they’re ok, but how long for I dunno. ‘Cept not in my case.
As mentioned, often seems to be an insulation issue according to some reports so a refurb or s/h may be on borrowed time. A couple of injector specialists mentioned on the caddy2k forum, inc Swadlingcote (other’s in Ireland). I was originally quoted 400 per injector (parts cost) initially (vs 230+vat at swadlingcote) but independent managed to get about 270 – 300 inc vat/rebate. Thats new ptices btw. Fitting about 170 +vat + some additional parts, the copper washer under both under one spreader bar has to be replaced so I took the plunge and replaced a pair. 10-15 miles later, one in the other pair went :/ (2012 and about 35k miles). Expensive week :/
StonerFree Membermboy – had confirmation in the pub tonight that this is the chap that comes recommended
Cant vouch personally for him, but my mate is a petrol (diesel) head and wont put up with any crap mechanics.
