Injector seal gone on Citroen Picasso

nino1

yellow engine warning light came on dashboard.
brought it to garage, who did diagnostic. said injector seal needs replacing.
says price can vary wildly, wont know until they look further.
then said that may not be cause of warning light.

i know nothing about cars so looking for advice.

if they did diagnostic for engine warning light should that not give definite reason for light coming on?

is it normal not to be able to give price for injector seal replacement? how much should i expect to pay?

thanks in advance

The diagnostic scan wont show up an injector seal leak, the black gunk around the injector is usually the hint for it!

In these cars the injector can get stuck in place if the leak has been going on a while. The carbon buildup sets rock solid and it makes removing the injector more difficult.

As for cost, the 3 seals needed come in at less than 10 euro. It is also advised to replace the injector stud bolts at the same time but a lot of garages don't do this. Labour wise, I have done a non seized one on my driveway in an hour. I had a garage remove a seized one and it took 2 hours.

For an indie expect 40 euro an hour, worst case three hours, plus 10 for parts.

You should hopefully have change of 130.

It is a DIY job if you have the tools. If it is the 1.6HDI engine you will need a 7mm hex driver to release the injector clamp, and a small female torx socket to remove the studs. Apart from that its a size 13 spanner for the high pressure fuel line, and a standard socket set 8mm - 17mm for the rest.

A few words of warning though:
1. Be VERY careful removing the plastic leak off hoses from the top of the injectors. They are delicate, and a broken one will ruin your day.
2. Use vaseline on the little green washer on said leak off hose...otherwise you will shred the washer.
3. Be gentle with the HP hose, the recommendation is to replace it every time it is removed, but you can get away with it if you are gentle.
4. DONT over torque the injector clamp nuts. I think its something like 12nm then 60 degrees. If you shear one of the delicate little studs then you are goosed.
5. If the injector is stuck then you can use the studs to ease it out. Remove the nuts, then loosen the injector studs a turn each while the injector is still attached. This will push it up and out of the hole. Make sure to replace the studs after this though as they might be damaged.
6. Good luck getting the copper washer out if it stays in the hole and doesnt come up with the injector. The best way I have found is to find a whilips screwdriver with a diameter similar to the hole in the washer then belt if through the stuck one with a hammer.

As ken said its a job that can turn into a nightmare i had never handled injectors before so bottled it also ther is usually a buildup of carbon that needs to be cleaned off as well so I just sent it to mechanic any damage to an injector will be pricey

I definitely wouldn't recommend an amateur to attempt to change a 1.6 HDI injector on their driveway. It's a recipe for disaster.
