MK4 Repair List - DIY or Garage - Help

[Red_Tekk]

Hey, new to this forum but just wanted a bit of advice. Have had my MK4 1996 Polo for around a year now and has been SORN for 6 months (money issues) Just put it back through it's MOT and have has failed due to 10 faults. Have had a quote from the Garage (reputable, not rip off merchant) of £656.60 inc VAT for parts and labour. This is out of the question as it is only a 1.0L and not worth anymore than £800/£900. Question is, the following faults are they DIY-able or are any of them specifically only for a Garage? Will be doing this as a project over the next 3/4months as I want to sell the car on for as much as possible rather than scrapping. Would you say I should just Scrap? Bite the bullet and pay a garage or DIY it? I'm handy with simple tasks on cars and have friends who can help but have no experience with a Polo.

Faults
1. Nearside Front Coil Spring Incomplete [2.4.C.1a](I presume it would be best to replace both?)
2. Nearside Rear wheel bearing feels rouch when rotated [2.6.1]
3. Nearside Rear wheel bearing has excessive play [2.6.2]
4. Offside Rear wheel bearing feels rough when rotated[2.6.1]
5. Offside Rear wheel bearing has excessive play [2.6.2]
6. Nearside (front to rear) Brake pipe excessively corroded [3.6.B.2c]
7. Offside (front to rear) Brake pipe excessively corroded [3.6.B.2c]
8. Offside rear Brake pipe excessively corroded [3.6.B.2c]
9. Nearside rear Shock absorber has negligible damping effect [2.7.5]
10. Exhause emissions carbon monoxide content after 2nd fast idle excessive [7.3.2b] (Needs new Cat)

The bearings and the brake pipes are the only parts I've never touched on a car, are they easy to replace or would I need a garage to do them?

Thanks in advance

not much there, and quite easy to repair by all accounts. to do the brake pipes, you first need to remove the old ones and take these along to a garage that has a quality flaring tool. they can then make up new pipes using copper or cuprinol brake pipes and new ends. you then bend these carefully to shape and fit them back onto your car. the brakes will then need to be thoroughly bled until you get a good pedal.
the rear wheel bearing are straightforward. you remove the rear wheels and drums, then remove the cap in the centre. remove the split pin and lock washer, undo the 24mm bolt and remove the hub. the old bearings are drifted out and new ones fitted, either by pressing them in , or using a socket or drift to carefully tap them into place. reassembly is reverse of removal, using plenty of wheel bearing grease. you tighten the nut until you can just feel the slightest bit of play, literally a gnats whisker, refit the lock washer and a new split pin. care is needed with the bearings and it is advisable to have a manual, or someone familiar with the job to hand.
before condeming the catalytic convertor, you should have someone perform a diagnostic check, and check the function of the lambda sensor inparticular. also check the exhaust for the slightest of leaks.
