From Andrews Coxs post on Facebook: This has been covered before using check straps from a C4 but this is a way cheaper option

Andrew Cox wrote ...
I had a rare experience today, a fix for the C6 that proved to be easier and much cheaper than I expected.

Problem - the door check strap doesn't hold the door open.

The first picture shows the offending part. The idea is, there are springs on both sides of the check strap, which engage in recesses to provide the hold-open action. The central part should be in the middle of the recess; the areas the arrows point to should be symmetrical.

The explanation is simple, as the second picture shows, the upper spring has rusted away.



There are two options here. buy a complete new assembly at £46.20 (front) or £38.96 (rear), or replace the failed spring.

I did a search on eBay for "door check strap". Up popped a very similar looking unit for a Vauxhall Astra ("H" OEM Numbers: 13107175, 516 0251) at £7.99, delivered.

First image is the new Asta Unit



The next picture is Astra unit, stripped. As you can see, the springs & associated bits are the same as the C6.




Now to change it you need to remove the door card to get access to the inner door and there are a few screws to contend with so you will need a couple of 'Torq' spanners. There is also a line of plastic clips which are sure to break so buy a pack of 5 (part 7473FL) (I needed to replace 6 so just missed one out )





With the door card removed you have to then remove the 2 nuts holding the door stay to the door frame and the Torq screw holding the stay to the A pillar. The fun part is manouvering out of the hole in the door




That hole will have a foam type cover glued on which needs to be peeled off but will tear so I threw mine away and put some spare Dynamat over it when I reassembled but Gaffa tape would do...

OK so the old stay is off so put it in a Vice and prise out the spring retainer with a screwdriver and a pair of pliers. The plate slides out toward the outside, the screwdiver gets is moving so you can get a grip to pull it out the rest of the way.




(Picture is shown stripping the new one as it was clean)
On mine the bottom spring was fine but the top had rusted through and snapped.



Fitting the 'New' springs involved using a G clamp and a small socket to compress it enough to start the retaining plate in the slot, then using the same clamp squeezing the retaining plate over the spring to keep it in place. I did fil the spring hole with Coppa Slip in an effort to slow future corosion.

Taking my time it took me around 1.5 hours in total (including cleanup afterward)

What you need is 1 X Vauxhall Astra ("H" OEM Numbers: 13107175, 516 0251) at circa £7.99 and a few spare trim clips at circa £7.65 for 5

As it's usually only the top spring that breaks on a C6 1 Astra stay might door 2 doors

Thanks for compiling Dave.

Andrew's find on the Astra part is a great piece of detective work. This is what makes the forum great.

Best regards,

Phil C.
