This video is on the Vauxhall (Opel) Insignia with the 2.0 litre diesel engine (A20DTH engine code). A common issue is getting a turbo over/under boost, MAF or other sensor issues where the car goes into limp and the engine management light (EML or MIL) comes on. Normally turning the ignition off and back on it will restore for a short time until you generally accelerate hard and it happens again.
The turbo pipes crack and will allow air to escape causing this fault. Typically the crack/damage will be at the back where you won't see it!
Replacing it for the same pipe from ebay:

Intercooler Turbo Hose Pipe Fits Vauxhall Insignia Mk1 2.0 CDTI 13242121, 860118
I'd also recommend getting a 75mm jubilee (hose clamp) for the lower end on the 'u-bend' as the original Vauxhall clamp is almost impossible to remove/refit without damage.

Great video. Followed your video and got the pipe in and out no problem. I had an inch and half split in mine. Cleaned pipe and gaffer taped it up for a temporary repair till new pipe comes. Thanks.

Is this something I’m able to do myself

Hello, Ive just Replaced My intercooler pipe but im struggling to re attach the Plastic U bend pipe as the Retention clip that was originally on snapped and the jubilee clips ive used won't keep the u bend on which makes my car loose power is there another way to fit the U Bend pipe at all?

@seanwallace1972

Mine broke off EGR is the pipe the same for my 1.6 cdti 136 ps if not any links.ive looked at lots of different pipes but can’t seem to find the correct 1

@davesanderson703

would a 70mm clamp be ok

@dikystayfly

hi, I changed my turbo pipe and the car works fine but the service light is still on my dashboard, how do I clear this?

@seanwallace1972

You mention about the scre you have to undo all the way,and spinning to separate the pipe,do you mean the pipe that joins the bent plastic end

@seanwallace1972

You used 2 jubilee clips together,are the single jubilee clips not availible for that size clip

Just saved me a turbo replacement, i had it booked in to be replaced as i was told it was that. After watching this i decided to remove pipe and check, it was split and now its running as it should after a temporary repair (new pipe on order). Thanks for the vid 👍👍

@LordTheodore04

@buda1986joe

@djantonswarve4439

@neildean7515

Great video. Thanks for detailed explanation. Your Icarsoft CR Pro scan tool looked great. Can you please do a future video on reading “ live data”. i would be particularly interested in your Zafira B(which i have too), which seems to have a problem reading live data on vauxhall/Zafira… I would love to see EGR/ DPF and fuel trim data.. this would make a great video.. thank again, kind regards…

No codes on my insignia 2010 diesel and no cracks on boost hose but loses power sometimes and also sounds like an exhaust leak but nothing detected. Dunno what to do. Don't want to get ripped off at Vauxhall garage so still searching for a workshop somewhere who knows what they're doing if you know what I mean

@fittermet

Hi,what were the symptoms before changing pipe. Did the car drive ok . Thanks

@hamzah0786able

Hi, good video, I have replaced the pipe on my insignia but I’m struggling to put the bottom part back in to the Intercooler connector. Should I unplug the top, so the bottom part gives me some play? How should it connect at the bottom part. Thanks
